to persist encryption keys? accross reboots?
<hyper_ch>
bpye: what do you mean?
<bpye>
So - I like the concept described in the article however I use ZFS' native encryption and my home server reboots very slowly (actual server hardware problems...) so I wonder if instead I could kill two birds with a singular stone - kexec would give me a quick reboot and if I can figure out a way to persist the ZFS encryption key across the kexec then I can avoid needing to enter the passphrase frequently
<hyper_ch>
how often do you reboot? oO
<clever>
bpye: if you `systemctl kexec`, then systemd will reboot the machine via kexec, the issue though is getting it to pass the keys over...
<bpye>
Actually, even that won't work for me because I'm stuck with BIOS boot... But I can get around that by calling kexec manually first, yeah, getting keys over is the tricky bit...
<bpye>
I guess the intent would be to allocate some pages in memory that we can retrieve the key from in the new initrd...
<danderson>
gchristensen: so, following your "erase your darlings" blog post, I'm wondering... What do you do about /etc/nixos?
<danderson>
That ends up in the root dataset for me, and being the configuration that gets applied, I can't easily define symlinks for it via the config that it contains, if that makes sense.

danderson: tankTest/encZFS/persist/etc.nixos 1.76M 3.50T 244K /etc/nixos --> I even use zfs mount for that
<bpye>
Hah... I think I can have an awful hack where I indicate that a memory region is nvram, and then during boot we attempt to mount and find keys there before falling back to SSH input which will also have to persist keys there
<bpye>
And during a kexec that region will be persisted because we didn't clear memory

i like the way awesomewm's tags and it tiling windows, it does floating windows well and comes with own status bar and notification system

but it feels a bit too heavy memory-wise for a solo window manager and the docs can be ... iffy at times and it's not as popular as i3, so there is less help for it

Too many moving parts.
<angerman>
Maybe I should enlist clever :-) he already has an account to the machine in question.
<srhb>
I think the default NixOS setup should only have ~/.nix-defexpr/channels_root, which points to /nix/var/nix/profiles/per-user/root/channels
<srhb>
In there, there'll be a nixos channel, which contains nixpkgs
<srhb>
And that should "just work"
<srhb>
(in other words, one way to break it is to delete or maybe even rename root's channels)

that file is recreated at boot based on the channel your booted system was built from

(Just clarifying that, because they were talking about network interfaces a while ago.)
<notgne2>
you can technically still use the results in Nix expressions though using buuiltins.readFile Miyu-saki
<notgne2>
not sure if it's a good idea, but one of my personal modules actually uses runCommandNoCC to generate a list of IPs for the wireguard module
<ixxie>
well here is the thing... I need to determine the network interface in order to add an IP to it, but this needs to be dynamic; clever recommended I create a dedicated systemd service for this, but learning now from symphorien that NixOS ensures a predictable network interface name, I feel that approach is overkill
<ixxie>
so I plan to determine the interface at build time. Only minus is that I must build on the target machine, but for the time being I can live with that and do something fancier in the future
<Miyu-saki>
It's not. You'd want to generate them on runtime. But let's be honest, it's morally okay to make something just work, rather than correct.
<simpson>
linarcx: I've taken a quick look at the package. I'm guessing that the aria2 derivation could be configured to build the library and changed to have a lib output.
<ixxie>
somehow all of this still seems more complicated than it should be, I am quite sure there are better tools for this that I don't know about
<Miyu-saki>
Technically, you can't determine the interface at build time, because Nix is not hardware-aware.
iyzsong has quit [Ping timeout: 260 seconds]
<Miyu-saki>
you can determine the interface at build time, on the first build. But it will stop working when you change hardware.
<notgne2>
my use case was at least still deterministic (it takes the server IP and uses the python ipaddress module to create subnet ranges excluding it), if you use a derivation to break purity like that it will be difficult, and that's probably for a good reason as it can be really messy to forget about or work around in the future
<Miyu-saki>
Which is ewll, somewhat okay, honestly.

Are impure derivatiions content-addressable?

<nschoe>
Hi everyone. I'm on 20.03, fresh install from a few weeks ago. My laptop SD card reader doesn't seem to work. Inserting the SD card inside does not show a /dev/mmcblk as it should be, and 'dmesg' doesn't even register it.
<nschoe>
'lspci' lists the reader as "Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01)".
<nschoe>
Is there something I should install or a nixos-option to enable?
<glittershark>
until I :b it
<glittershark>
clever: that's what I thought... but it isn't happening
<clever>
glittershark: and when you try to build a derivation, all of its build-time deps get built
<glittershark>
clever: again, that's what I would expect to happen, but it isn't
<clever>
glittershark: so only :b, nix-build, nix-shell, and nix-env can cause the build to actually start]

<simpson>
Meh. I mean, yes, I was flippant. Reading https://nixos.wiki/wiki/Nix_channels, I think that the channel does not update until the entire package set is cached, and the cache probably takes time to fill, although maybe three days is a long time for that.

Alright so is there an easy way to grep the output from nix-review (or nixpkgs-review... cant remember) so I can see which packages are failing as a direct result of my changes?
<evanjs>
I want to compile a list of packages that break as a direct result of my bump for pillow so I can address those directly. Filtering out such packages by doing individual `nix build`s will likely drive my insane... should I ever have enough focus to get it done

If both Hydra and GitHub go down, you're SoL. There's something to be said for single points of failure, but that isn't really on-topic for #nixos

is there a way to create a shell environment in which I can build binaries that'll run directly on ubuntu, i.e. no funny rpath to the dynamic loader?

This creates a binary that doesn't need a nix installation to run ^

But by default, Nix binaries run on all distros, assuming you use Nix to install them

that's good for what it is, but I'm asking if there's a way to construct an environment where I can compile a binary that will run on another distro directly, provided that I know what versions of the dynamic libraries I need are available
<Ralith_>
(which are few, just the regular gcc runtime stuff)

something like how the nix package for steam emulates an ubuntu environment

Ralith_: you need to use the libraries that ubuntu provides, or you run the risk of compatability problems

again, same architecture

you could just use patchelf to undo the rpath stuff

you can handle user-specific configs in ~/.config with nix too (see home-manager)

basically when a nixos update breaks something you can just reboot into the previous state

Yaniel, Suppose we keep track of every version of every package in a json file. Then if things break, we revert back to those exact versions...How nix is diferent from this?
<Yaniel>
with debian you have to untangle the mess manually
codygman has joined #nixos

in addition to that nix also isolates every package from everything except its dependencies

energizer: I hate yaml with a passion..
<energizer>
adisbladis: sure, but most languages can output yaml, most cannot output nix
<adisbladis>
energizer: If you're generating things you're better off just outputting json

energizer: yaml is needlessly complex, suffers from portability issues, it's barely human readable (anchors?!?! such a shitty "feature")
<energizer>
dude i know :)
<adisbladis>
Tbh if you need deduplication you probably want functions :)
<adisbladis>
Good :)

substitution of '/nix/store/11b3gwnnj9nd61d0kh6kg42l5c7468b4-dhall-1.31.1': trying next substituter
<keithy[m]>
path '/nix/store/11b3gwnnj9nd61d0kh6kg42l5c7468b4-dhall-1.31.1' is required, but there is no substituter that can build it

Hmm... Anyone seen any other Skylake devices where booting without i915.modeset=0 results in a black screen as soon as i915 is loaded?
<bpye>
This is a Chromebook specifically, I don't remember needing this sort of hack before though...

Hi! so ughh how to use the flake-support branch of NixOps properly? I assume it doesn't support custom nixopsDefinitions.<something> attributes, only the default one
<vika_nezrimaya>
what about physical.nix? wanted to try the split definitions for the first time, my previous setup contained everything in one file
<abathur>
curious if anyone's dealt with a similar python-packaging pickle; I wrote a setup.py to build someone else's code which uses python for development but is distributed as a binary without pip. It has multiple dirs w/ __init__.py, used from other packages/modules without a prefix. I'd like to force a prefix on it; anyone know of a better way than extensive substituteAll? :)

vika_nezrimaya: not sure myself; may want to give #nixops a try if no one answers here
<abathur>
energizer: would prefer to avoid that if there's a way to hack it?
<energizer>
abathur: it's python, there's always a way to hack it :P

energizer: since he may add new modules, delete them, etc.; if I can force all imports to check the package I'm forcing in (but keep imports outside the package from falling over...)
<keithy[m]>
should sshagent be running by default?
<vika_nezrimaya>
abathur: #nixops is almost empty tho :c
<keithy[m]>
I am looking at nix pkgs and I see lots of descriptive docs like mkOption { type description etc. Where is this displayed/used?
<energizer>
vika_nezrimaya: small tool channel often means "all the maintainers are in this channel" :P
<abathur>
vika_nezrimaya: perhaps, but your message will be visible to everyone idling there when they come back; here, it's going to be hidden in their scrollbacks in ~5-10m
<vika_nezrimaya>
let's hope #nixops senpais are gonna notice me
<quinn>
energizer: you'll probably have an even easier time writing your config file in nix, but if you must write it in something else, you should do just dhall -> nix. i'm not sure how json would figure, but i can't imagine it wouldn't create any problems with typing and formatting.

Ah I worked it out, kernel 5.4 appears to be broken but that's the default for 20.03, updating to 5.6 fixed my issues
<armin>
so what do i use if all i want to do is control the contents of a file in some home directory on the live cd i create? is there a simple stanza i could add in iso.nix?

armin: oneshot service?
<Raito_Bezarius>
or home-manager?
<Raito_Bezarius>
you can control a home from system config.nix
<armin>
Raito_Bezarius: i use home-manager actually on my desktop machine, but i have no clue how to do that one thing, control the contents of some simple config file, when building a live cd with nix-build
<Raito_Bezarius>
armin: with home-manager?
<armin>
hm

without

you'd need systemd
<Raito_Bezarius>
armin: but what is it exactly?
<Raito_Bezarius>
a simple file?
<Raito_Bezarius>
a dir?
<Raito_Bezarius>
oh, a config file
<energizer>
armin: you can do it in activationScripts
