@aanderse:nixos.devaandersei can't at the moment, though I'm sure there are a number01:28:44
@adam:robins.wtfadamcstephens I’m not sure what the impact to releases is. mkg20001initially created the lxc-container file it seems :)  01:29:09
@aanderse:nixos.devaanderse ah they would have something useful to say I'm sure ping mkg20001 ... whenever you have a chance to comment i would greatly appreciate it, specifically why lxc-container.nix is a file to be imported rather than a nixos module 01:30:57
@mkg20001:mkg20001.iomkg20001the import idea came from qemu doing something similar01:33:35
@mkg20001:mkg20001.iomkg20001there's no real reason why it's not just virtualisation.lxc.container-guest.enable = true; or similar01:33:57
@aanderse:nixos.devaanderseah so it was precedent based thank you for the information!01:34:22
@aanderse:nixos.devaanderseok so if i were to turn lxc-container.nix into a module i have everyone's support?01:35:19
@mkg20001:mkg20001.iomkg20001yes. we can make the file a stub that issues a warning and sets the required options01:35:51
@aanderse:nixos.devaandersegreat thanks everyone01:36:38
@adam:robins.wtfadamcstephens Yes I’m on board. I don’t love the UX of requiring an import from modulesPath  01:36:48
@aanderse:nixos.devaanderseyeah, it is a little bit jarring compared to the rest of the system01:37:47
@adam:robins.wtfadamcstephens As mkg mentioned, it’s a common pattern for these profiles, but that doesn’t mean it needs to stay that way  01:38:54
@aanderse:nixos.devaanderseyeah, good point01:39:08
@aanderse:nixos.devaandersebtw, is anyone using the combination of terraform/opentofu, lxd/incus, and nixos here?01:41:27
@adam:robins.wtfadamcstephens I use opentofu with incus (and was using it either lxd too) 01:44:34
@adam:robins.wtfadamcstephens * I use opentofu with incus (and was using it with lxd too) 01:46:09
@aanderse:nixos.devaandersehow much friction do you find in combing these technologies together? at work we are using this and the friction has been higher than i would like01:46:27
@adam:robins.wtfadamcstephens I would rather not use opentofu if I had a native nix alternative.   01:47:24
@aanderse:nixos.devaanderseyou mean like nixops-ish, right?01:47:58
@adam:robins.wtfadamcstephens I actually use terranix though so I’m still writing nix code 01:48:02
@aanderse:nixos.devaandersedoes terranix integrate nicely?01:48:32
@adam:robins.wtfadamcstephens
In reply to @aanderse:nixos.dev
you mean like nixops-ish, right?
I’ve never used nixops, so I’m not too sure about it   
01:48:42
@mkg20001:mkg20001.iomkg20001 nixos-rebuild --flake .#host --target-host root@your-machine is what I use for my machines after they're created 01:50:24
@adam:robins.wtfadamcstephens I think I envision something like microvm.nix that configures what resources incus should have, but then also doesn’t tightly couple the guest configs to the host  01:50:43
@adam:robins.wtfadamcstephens I have a homegrown deployment tool but it’s effectively using nixos rebuild target host  01:51:18
@mkg20001:mkg20001.iomkg20001
In reply to @adam:robins.wtf
I think I envision something like microvm.nix that configures what resources incus should have, but then also doesn’t tightly couple the guest configs to the host 
there is already have the virtualisation.diskSize, etc options from qemu which may be what you want. that could be generalized.
01:52:01
@aanderse:nixos.devaanderseah01:52:12
@aanderse:nixos.devaanderseyeah so i found myself needing terraform resource values in my nixos config... but at the same time needing nixos values inside my terraform config01:53:15
@aanderse:nixos.devaandersethis is something nixops did well01:53:32
@aanderse:nixos.devaandersei hacked a little script together and am trying it out for deployments01:53:59
