dhess yeah I'm trying to remember how to use the activation script in home-manager
<dhess>
ldlework: So you can change permissions (or even just copy the files rather than symlinking them) in the activation script
<ldlework>
Well I wouldn't copy the files since then I'd have to keep the keys in my git repo
<ldlework>
And I like to publish my dotfiles
<ldlework>
Hence the use of the environment
<ldlework>
But yeah gotta figure out this activation script
<Lisanna>
ugh, what happens when you have a stack that dynamically links against eachother and you don't want the entire thing to be rebuilt every time you make a small change to a bottom-level component?
<dhess>
you could keep them outside the repo.
<Lisanna>
and you just want the links to change
<Lisanna>
does nix have anything for making this not be such a huge pain
<ldlework>
dhess do you know how to utilize the activation script? To add things to it?
<dhess>
ldlework: I don't use home-manager. nix-darwin has a similar concept and I do use that but I have no idea whether they're functionally similar
<ldlework>
Well how do you use it there?

If I installed a package from git, is there anyway to recover what commit the package was built from?
klntsky has joined #nixos
<Lisanna>
ldlework what do you mean "installed a package from git"?
<ldlework>
Though honestly, its probably just because I am stupid
<Lisanna>
bring the package into scope in a nix-repl and evaluate package.src.rev
<ldlework>
Lisanna you know how you need the rev and sha256 for fetchFromGithub?
<ldlework>
There was some nix trick for getting the sha256 and rev, but its been like a year
<ldlework>
you... wouldn't happen to know those tricks?
<Lisanna>
ldlework you mean nix-prefetch-git?
<ldlework>
Perhaps?
<ldlework>
:)
<ldlework>
I'll google that
<Lisanna>
not sure if that's a "trick" though...
<Lisanna>
...more like the way to do it if you're not a lazy person
<ldlework>
haha
<ldlework>
There's an even lazier way?
<iqubic>
The trick I use for getting the sha256 is TOFU. "Trust on First Use" Where I basically give a dummy checksum, and when the compiler tells me what checksum it wants, I just use that.
<clever>
!tufo
<Lisanna>
if you're a lazy person, you put in a fake sha256 and watch the drv build fail, which will tell you what it's supposed to be
<clever>
!tofu
<{^_^}>
To get a sha256 hash of a new source, you can use the Trust On First Use model: use probably-wrong hash (for example: 0000000000000000000000000000000000000000000000000000) then replace it with the correct hash Nix expected.
<iqubic>
That is what I just said. Is it not?
<clever>
this one also includes an example hash
<iqubic>
Oh.
<Lisanna>
yeah... it won't work if the length isn't right
<iqubic>
How long is a sha256 supposed to be?

depends on how its encoded

How can I specify a subdirectory for callPackage, fetchFromGitHub?
<Lisanna>
are there any safe(-ish) ways to either duplicate a /nix/store path and have all the references to itself changed to the new copy, OR build a package such that it supports that without having to do anything special?
<Lisanna>
normally, duplicating a /nix/store path which is the result of some build that depends on itself will end up with all sorts of references pointing back to the original, and I don't want that
<Lisanna>
I guess since some of those references are going to be in binaries, that the new name has to be the same length as the old name?
<Wizek>
clever: but so far i get this error: `*** found zero or more than one cabal file ([]). Exiting.`
<Lisanna>
clever is there a reason why substituteInPlace wouldn't work?
<clever>
Wizek: cabal2nix may not even find the cabal file at that point
<Lisanna>
I tried that and it seemed to corrupt the elf, even though I checked to make sure the names were the same length
<clever>
Wizek: instead, try doing "${fetchFromGitHub { ... }/foobar" to make a path to the subdir, then pass that to cabal2nix
<clever>
Lisanna: why are you trying to copy paths like that?
<Lisanna>
clever so I can hot-swap dependencies
<Lisanna>
one of the upper-level packages in my stack takes like 10 minutes to compile and the result is huge, I can't afford to recompile and re-deploy it every time a small library underneath it changes
<clever>
Lisanna: there are already tools in nixos to do exactly this
<Lisanna>
so if A depends on foo and I want to change it to depend on bar, I just do replaceDependency { drv = A; oldDependency = foo; newDependency = bar; } ?
<Lisanna>
and that will work as long as foo and bar have the same length of names?
<clever>
Lisanna: i think so
<Lisanna>
Ah, replaceDependency is not mentioned anywhere in the nixpkgs manual, no wonder I've never heard of it!!
<Lisanna>
this is awesome, thank you
<clever>
its in the nixos manual
<clever>
yet the code is in nixpkgs
<Lisanna>
I read the nixpkgs manual a lot more often than the nixos manual ^^
<Lisanna>
this basically solves all of my problems
<Lisanna>
I'll be able to delete so much code...
<Lisanna>
wait, this is safe to use on packages that reference themselves, right?
<abathur>
I've been having trouble wrapping my head around profiles and efi boot entries, but I'm mostly convinced now that the trouble is because something isn't working right with my efi entries
<samueldr>
abathur: new generations aren't showing up?
<abathur>
yeah, and I can't clear old ones no matter how many recommendations I try
<Lisanna>
what does builtins.unsafeDiscardStringContext do?
<clever>
Lisanna: it discards the string context
<Lisanna>
x_x
<clever>
Lisanna: every string in nix has some context attached to it, that says what derivations it depends on
<abathur>
I had to go over the install several times because I was having instability issues related to ryzen and the kernel, so it wouldn't surprise me if I messed a few things up one time through or another
<Lisanna>
what derivations the /string/ depends on?
<clever>
Lisanna: yes
<Lisanna>
you mean if you write "${somepkgs}"
<clever>
Lisanna: yep
seanparsons has quit [Read error: Connection reset by peer]
<clever>
Lisanna: and when that string it placed into another derivation, nix combines the context from every string, to form the build-time deps of the new derivation
<iqubic>
Is there a way to install lisp documentation from Nixpkgs?
<iqubic>
Sorta like we can do with haskell docs?
<Lisanna>
so why would you want to discard it?
<clever>
Lisanna: one min
<Lisanna>
(I'm trying to understand the replace-dependency.nix implementation, and it uses it quite a bit)
<clever>
Lisanna: and that contains the path to the toplevel package
<Lisanna>
okay, so you discard that context so that your $out/command-line string doesn't try to pull in config.system.build.toplevel as a build-time dependency, which I guess would make the build a lot slower?
<clever>
Lisanna: it would also become a runtime dependency
<clever>
so when you copy the product around, its copying the OS around twice
<Lisanna>
this sounds like black magic. OK, so now the obvious naïve question: how on earth does that work
<Lisanna>
I mean, how is it safe to get rid of that... doesn't it need it?
woffs has quit [Quit: Gateway shutdown]
<clever>
i'm already embeding my own copy, in the form of a squashfs containing the entire thing
<clever>
and i have scripts that mount it to /nix at bootup
<Lisanna>
(I'm guessing I can't just call unsafeDiscardStringContext willy nilly on everything)
<clever>
if those scripts didnt exist, it would fail at runtime, because the path doesnt exist
<Lisanna>
OK, so using unsafeDiscardStringContext won't ever break build-time, but it might break runtime
<clever>
it may also break build-time
<clever>
those paths wont be added to the nix sandbox

Does github provide an API with checksums for tarballs? Or is the only way to find this by downloading and computing it yourself?
<vaibhavsagar>
adisbladis: I'm not aware of any API github provides
<adisbladis>
:/
<vaibhavsagar>
I thought nix-prefetch-url --unpack does something different to curl archive.tar.gz anyway
<vaibhavsagar>
so the checksum you'd get from github might not match the Nix-computed checksum even if they were to offer it
<adisbladis>
vaibhavsagar: This is not strictly nix-related. I was just hoping that someone here would have the knowledge.
<vaibhavsagar>
fair enough
<adisbladis>
But it seems like they dont have that kind of API
<Lisanna>
clever so, does your $out/command-line end up containing a reference to a package that doesn't exist? since "systemConfig=${config.system.build.toplevel}", but you don't want to actually include config.system.build.toplevel, so is that value set incorrectly?
fragamus has joined #nixos
<Lisanna>
so that'll resolve to "systemConfig=/nix/store/blah-toplevel", but you don't really want /nix/store/blah-toplevel since it's huge and you have a compressed version of it somewhere else
<clever>
klntsky: yeah
<clever>
Lisanna: yeah
<Lisanna>
OK, then why would you have ${config.system.build.toplevel} in your string at all? Why wouldn't you point it directly to the compressed version?
<Lisanna>
do you change it later?
<clever>
Lisanna: i need the path it unpacks to
<Lisanna>
or does /nix/store/blah-toplevel become valid later?
<Lisanna>
OK, so you use unsafeDiscardStringContext when you need the path to something without any of its contents, possibly with the intention that you will use its contents *later*, and that something will cause it to become valid later
ryanartecona has joined #nixos
<clever>
yeah
<clever>
and its only really of use in weird situations where nix isnt aware of how you are making it valid later
<Lisanna>
...in the case of replaceDependency, the way you make it valid later is "nix-store --restore"
<Lisanna>
I guess
<Lisanna>
or, no, maybe it just needs the name of the path

ok, not so bad then... it's a good safe-guard

<sphalerite_>
Ulrar: use nix-build '<nixpkgs/nixos>' -I nixos-config=path/to/your/configuration -A config.system.build.isoImage and you'll get a result symlink. Then you can cp result/*.iso somewhere else or whatever
<ij>
typetetris, well you can refactor the override function outside and reuse it instead of retyping it with a let construct.
<sphalerite_>
ij: what about just sorting them by name?
<Ulrar>
Ah, didn't know about the symlink, it doesn't say that on the output
<Ulrar>
and I don't have access to the build machine so hard to check, but I can try to use result/web.iso as the path I guess
dan_b has joined #nixos
<sphalerite_>
Ulrar: or since nix-build outputs the path on standard output you can do cp $(nix-build <...> --no-out-link)/*.iso wherever
<ij>
sphalerite_, That would mostly work, but I wouldn't mind having deeper comparison either. :)
<sphalerite_>
ij: do you know about Gabriel Gonzalez's nix-diff?
<sphalerite_>
typetetris: I'd recommend not doing that at all, and instead modifying it in a nixpkgs checkout and making a PR :)
<Ulrar>
sphalerite_: I see, I could just have a script read the output indeed. Well I'll try the result/ thing first, just in case, but thanks !

And I assume nixpkgs/nixos/modules/installer/cd-dvd/iso-image.nix is the best way to make a simple iso image ? It seems to fetch strange things like xscreensaver for some reason

The python neovim-0.2.1 need msgpack >= 5.0 shoud I create a msgpack-5 derivation and leave msgpack (currently sitting on 4.7) alone to not break other dependencies?

<sphalerite_>
there shouldn't be a problem with that. You may also need to adjust NIX_PATH accordingly though
<sphalerite_>
I prefer to just avoid nix-defexpr completely because it's horrible by aliasing nix-env to nix-env -f '<nixpkgs>
<typetetris>
sphalerite_: Could you explain more of your workflow? How can I get rid of typing -I <stuf> and -f <stuff> all the time?
<sphalerite_>
ij: oh yeah. You could compare their output paths since those are based on the hash of the derivation. That wouldn't take into account the meta and passthru fields, but I think it's a reasonable notion of sameness to say that two derivations which produce the same output are the same
<sphalerite_>
modulo fixed-output ones maybe.
<sphalerite_>
Does nix-diff not cover what you need though?
<ij>
You were thinking I could extract the comparison function from its source?
<sphalerite_>
I was thinking you could just use it directly. I don't know what you're trying to achieve (XY)
<sphalerite_>
typetetris: I use nix-env quite rarely, only to update what I have installed in my profile (quite obviously)
<sphalerite_>
typetetris: most of the time if I'm making some changes to nixpkgs I'm in ~/nixpkgs and just do nix-build -A foo to build whatever I'm working on since nix-build defaults to default.nix in the CWD
<typetetris>
ok, I try that.
<Ulrar>
sphalerite_: Doesn't look like result exists, at least for me
<typetetris>
the build of the neovim python packages fails on me with `Could not find a version that satisfies the requirement msgpack>=0.5.0 (from neovim==0.2.1)` but it lists msgpack in its propagatedBuildInputs and I changed the version of the python msgpack derivation to 0.5.4 ?

Hi. I have a problem. "nix-instantiate '<nixpkgs/nixos>' --argstr system i686-linux -A system" does not propagate system=i686-linux through all dependencies anymore (since yesterday?) and produces different things on x86_64 and i686. For instance, the dependent busybox.drv contains ("system", "x86_64-linux").
<manveru>
woffs: any chance you can bisect what commit in nixpkgs caused that?
<joepie91>
wasn't there a way to have nixpkgs produce a Docker image of a given NixOS system specification?
<joepie91>
I vaguely recall something like this
<manveru>
for a whole nixos?
<simpson>
joepie91: Unlikely, since systemd doesn't work in Docker. There's dockerTools in nixpkgs if you don't need systemd.
<gchristensen>
I don't think so, because there would be no service management.
<gchristensen>
^ simpson
<manveru>
there's nix-docker... which gives you nix-daemon inside of docker and the basics you need for a nixos system... but no systemd

<genesis>
i just wanted to look @ buildenv, it seems it has a lot of dependancies and no parameters hum
<sphalerite_>
the right way to build nixUnstable from its source repository (e.g. if you need a feature that was introduced since the last bump on it in nixpkgs), the right way is to override the nixpkgs one or to build it using the release.nix in your checkout of the repo
xcmw has joined #nixos
<dtz>
note you'll need to already be running nixUnstable to use its release.nix
<genesis>
that is, because i've tried without success
<shlevy>
Note that if you're trying to *locally* hack on nix, you can use nix-shell in the source repo, do bootstrap.sh and ./configure $configureFlags, then your eventual make install will install into $PWD/inst
<simpson>
genesis: shlevy's advice is probably worth paying attention to, as they're the only one of us that actually hacks on Nix, I think~

if you tried with nix prior to the nix
<sphalerite_>
dtz: oh hi :D sorry to pester you again, but any news on publicly usable ALLVM?

<simpson>
Oh hey, nix-bundle has AppImage support. Never mind. Try out nix-bundle.
<genesis>
i try but i don't get it works AND what i want to do is between them both ;)
<sphalerite_>
I think the thing with nix-bundle is that it comes with the weaknesses that AppImage has on its own too, which is that dependencies are rapidly outdated and the images are huge. It usually ends up making more sense to just use nix on the target systems.
<simpson>
There is no "both" with Nix. There is only Nix.
<genesis>
sphalerite_ : yes BUT have a working nixpak that works everywhere will come people on nix
<dtz>
It's amusing that it supports appimage since appimages don't always work on NixOS. Or they didnt previously.
<genesis>
because on appimages, they spend time writing awful script to build and populate their directory
<simpson>
genesis: Oh, ew, don't do that. It will be *much* better for people to have a real Nix installation.
<sphalerite_>
genesis: not really, since it doesn't provide any of its advantages.
<simpson>
Anyway, if nix-bundle doesn't work perfectly for you, hack it until it works and send in PRs. Failing that, have short reproducible test cases (see http://sscce.org/ for examples) and file issues.
<simpson>
But it looks quite good. It looks so good that I'm thinking about adopting it right now.
<genesis>
some people won't change their distribution and still want a snappy/flak or appimages style of binary
<sphalerite_>
you don't need to chagne your distribution to use nix
<simpson>
Who cares about "some people"? What's your use case *today*?
<duncan^>
simpson: It is far worse than that - the AppImage is in a weird format that is a combination of ISO CD format and something else. And it bundles *everything*. And then they manipulate the binary header to make it appear as an executable

I think nixpkgs needs a general-purpose "editDerivation" function. I'm sure most of us have written something like this at some point - where you just want to do a runCommand on a derivation but otherwise keep everything else the same
gfixler has joined #nixos
<Lisanna>
"edit" is misleading though, since it would still produce a new derivation with a new $out
<gchristensen>
like overrideAttrs?
<Lisanna>
gchristensen sort of, but for arbitrary derivations, and without regenerating it

so like stdenv.mkDerivation { src = drv; ... }
<Lisanna>
LnL yes, but that is limited, since you have to write a bunch of stuff like cp -rH $src $out or wahtever the correct cp command is

<Lisanna>
much better way: take the implementation of replaceDependency, remove the oldDerivation newDerivation functionality so that it just fixes recursive references, and then accept as input some arbitrary shell commands to run after the nix-store --restore $out
<Lisanna>
ah, that'll work only on derivations which are single files

anyways, I'm going to write an implementation of editDerivation like I described, it'll be usable on arbitrary derivations. If I can get approval, I'll upstream it

<MichaelRaskin>
That's true.

samueldr: I am trying.
<samueldr>
I'm trying too!
<samueldr>
but I had a rubber-duck moment, while trying to ask my question
<samueldr>
(may have found my issue)
<Lisanna>
samueldr toppler I /tried/
<jsgrant>
Idk, the older I get (and probably a good thing, but certainly a sad thing) the more of a cynic I become -- especially when it comes to the market relevance of "the best stuff".
<dhess>
gchristensen: you could start there, and then if you got traction, once people are familiar with Nix and the way it works, you could then attempt to pivot to a pure Nix approach
<LnL>
I use it to build an image with nix inside of it :p
<dhess>
"embrace and extend" and all that
<gchristensen>
=)
<jsgrant>
But I also REALLY got burnt (probably by/from myself) on Lisp and the like; Still probably just sour on that. :^P
<toppler>
jsgrant: Oh, that cynicism hit me at age 19, when I found myself following around grumpy Lisp hackers at an impressionable age.
<MichaelRaskin>
«That is how you build Docker containers sanely. In fact, you can build other stuff, too. In fact, are you sure you do need docker and not just mere nsjail?»
<samueldr>
(in my particular use case it has to run in a docker vm and I'm not in control of that part :[)
<jsgrant>
toppler, Ha; Similar treks -- Except I was REALLY overly optimistic and lived in a near absolutist Lisp env & was starting to work backwards from a Emacs-as-a-desktopenv , to distro, to os.
<MichaelRaskin>
The problem is that five years ago there still was no credible language to replace the good parts of Lisp even if with a different balance. Nowadays — maybe Julia can mature into that niche.
digitalmentat has joined #nixos
<jsgrant>
Was around that age too.
<MichaelRaskin>
jsgrant: Hm…
<MichaelRaskin>
Remind me around 19th…
<jsgrant>
MichaelRaskin, Hm?
<jsgrant>
Oh!
<Lisanna>
docker on nix is probably always going to be limited, because nix stores the images as compressed files on disk rather than in a docker database
<jsgrant>
Sorry, missed earlier msg
<digitalmentat>
how does Nix track dependencies of a derivation? I know that if you interpolate a derivation into, say, the builder of another the "input derivation" is built in order to satisfy the builder it's being interpolated into
<Lisanna>
so a nix solution will also be heavier on disk space
<jsgrant>
MichaelRaskin: Tooling was kind of shit too; Not too long ago in CL.
<Lisanna>
and docker already sucks royally on that front
<digitalmentat>
but does Nix do any additional "tracking" of that input derivation?
<jsgrant>
Now Roswell & Quicklisp has helped A LOT.
<digitalmentat>
or is that specifically what buildInputs is for?
<jsgrant>
Still very niche, obviously.
asuryawanshi has quit [Ping timeout: 240 seconds]
<Lisanna>
digitalmentat runtime deps of a dependency are computed by scanning the bytes of the derivation for /nix/store paths
<MichaelRaskin>
jsgrant: well, you can search for «Lisp in the middle»; I am currently preparing a submission for this year ELS. It does concern Lisp, Nix, and what parts of OS you want to manage.
<digitalmentat>
Lisanna, well there are runtime and buildtime deps - I'm specifically talking about buildtime deps
<Lisanna>
oh, oops
<digitalmentat>
for instance, if I have a computer that cannot talk to the internet and I want to build a new configuration from a closure with "everything included"
<gchristensen>
its a good thing hetzner cloud doesn't mind churning VMs... I say, destroying then launching his 5th time today
<samueldr>
only 5?
<gchristensen>
50th*
<dhess>
gchristensen: are you happy with it so far? I am tempted to move some VMs there
<jsgrant>
MichaelRaskin: Problem is I have an absolutist if not generally too excitable kindof mind; It makes it really hard for me to detach and be moderate.
<jsgrant>
Is actually pretty obnoxious, really.
<gchristensen>
dhess: its cheap :)
<dhess>
gchristensen: what about good?
<samueldr>
let's hope it's billed at the minute and not the hour or longer :)
<MichaelRaskin>
jsgrant: yes, my lightning talk was «if you want a Lisp OS ever again, you need to pick your battles, that's why, that's how»
<dhess>
cheap/fast/good pick any 2
<gchristensen>
dhess: all I know is it is cheap and provisioning new instances takes just a minute or so
<dhess>
gchristensen: do they give you IPv6? Specifically, do they give each instance a routed /56 or larger?
<gchristensen>
dhess: they seem to give a /64
<sphalerite_>
digitalmentat: I think nix tracks dependencies during evaluation through the "string context" mechanism. Not sure though.
<jsgrant>
MichaelRaskin: That's so hard to do though in practice man -- because typically the people interested in such things in the first-place, have really high-bars in terms of purity tests; Prohibitively so.
<dhess>
gchristensen: well, that's better than most, anyway
<jsgrant>
I've been getting a 'little better' at picking battles, technologically; But I was/am so bad at it at start -- that still probably less than "the norm"; Do think there is a certain kindof programmer that has some kind of pathology that lends to this though. :^P
<sphalerite_>
digitalmentat: no. buildInputs is just one way that a derivation can end up depending on another. It has no special meaning on the nix level, it's only handled by stdenv.mkDerivation in nixpkgs
MinceR has quit [Ping timeout: 264 seconds]

sphalerite_, so I have an exported closure that I'm trying to build a configuration from on a machine without internet access
<sphalerite_>
digitalmentat: you may be looking for nix-store -q --references on the .drv file
<digitalmentat>
dbus-1 depends on libxslt
<sphalerite_>
ah right. Hm
<digitalmentat>
but libxslt isn't included in the closure
<digitalmentat>
now, adding it to the closure is straight-forward
<digitalmentat>
I'm just trying to make sure I have my understanding of how this is working, right
<sphalerite_>
so you only need to build the one derivation on the unconnected machine?
<jsgrant>
That's when you market your ideological-leanings as "enthusiast". X^D
MinceR has joined #nixos
<digitalmentat>
dbus-1.drv is a depenency of an etc.drv I think
<digitalmentat>
in other words, nix-store --export isn't picking up the fact that libxslt is a dependency of dbus-1
<pie_>
how do i do that in the context of dmmpython = pkgs.python27.withPackages (ps: with ps; [ numpy pyusb matplotlib ]);
<MichaelRaskin>
jsgrant: well, there are people who are interested in trying to do at least something.
<sphalerite_>
digitalmentat: oh right. See the man page for nix-store, it mentions that --export doesn't produce the closure and how to do so
<digitalmentat>
okay I will read it, thank you for the tip
<jsgrant>
MichaelRaskin: Yeah, there's nothing wrong with throwing your hat in the ring -- if you can manage it and your time/energy properly; Not end up a Terry A Davis-like character; Which I started to notice myself slowly shifting towards.

samueldr: an SBCL instance with a daemon loaded that accepts requests over a socket and makes access decisions
<samueldr>
cool
<jsgrant>
In-fact my inability to read anything more than a few oneliners in most other langs, I even had a little exposure to prior, noticed there was a problem.
<MichaelRaskin>
And it uses an access criterion that somehow is hard to get with default sudo installations.
<NeedABitOfHelp>
I managed to get the configuration.nix file working and got it to compile with all the modules(it only comes with 2 by default)
<jsgrant>
Idk, still very weird looking back on all that (sorry for chanspam).
<gchristensen>

<NeedABitOfHelp>
But, when I try to run it, polybar still only works with 2 of the 5 modules
<jsgrant>
gchristensen, -> #guix ?
<gchristensen>
no no, let's keep it nixos! :)
<MichaelRaskin>
gchristensen: I think it is time to try reviving #nixos-blah
<MichaelRaskin>
It even exists
<samueldr>
isn't it ##$channel_name that's the off-topic channel, the convention on freenode?
<gchristensen>
##channel means non-official, not offtopic
<gchristensen>
there is no #php but there is a ##php because PHP.net doesn't declare Freenode its official home

so if you install using nix-env -iA nixos.polybar you're installing the standard polybar. What you want to do is make sure you don't have a polybar in your user env, and nixos-rebuild switch to ensure that the polybar from your configuration is active

Quick NixOps question. I am considering moving some services into EC2. Some of these will be 24/7, so I want to use reserved instances for those.
<dhess>
My understanding is that with EC2 I pay up front for, say, N reserved instances of type X, and basically I get a credit for those
<dhess>
so when I deploy N instances of type X with NixOps, those will be billed at the reserved instance rate
<dhess>
is that right?
hiratara has joined #nixos
<chreekat>
dhess: that's right, the 'reservations' are applied at billing time, and it's confusing because (through the AWS UI) there's no way to actually link a particular reservation to a particular instance
<chreekat>
someone please correct me if I'm wrong
<dhess>
chreekat: thank you.
<chreekat>
dhess: make sure the reservation and the instance are in the same region

i've PR pending and merging on squashfuse, and i know i'll be using this very soon , i wonder how much it costs to lose a contributer for 3 lines of useless code between have 3 lines of code that is not what we write at the place of the man who spend hours to write it.
<genesis>
sorry but i'm a bit fed up at this time of merge then unmerge code of contributer on such non crucial thing as a non used before derivation.
