 David Arnold (blaggacao) | The @installBootLoader@ can come from different places, afair. | 21:11:48 |
 @teutat3s:pub.solar | in our case it would be grub https://github.com/NixOS/nixpkgs/blob/5605b561ce51d3e6b5a56566d6e58fe3e5b36970/nixos/modules/system/boot/loader/grub/grub.nix#L726 | 21:12:26 |
| David Arnold (blaggacao) | Just saw initialRamdiskSecretsAppender... | 21:14:56 |
| David Arnold (blaggacao) | Maybe an agenix grub module need to be written? | 21:16:28 |
 b12f | Perhaps. A hook that can start services before the bootloader init might be more general-purpose though | 21:37:19 |
| b12f | You'd need health or ready checks however, the complexity could become too big to justify the effort | 21:38:05 |
 genadij.udarov | Hey, I'm very new to nixos, let alone devos. I've stumbled upon a note[1] in the documentation: It is convenient to have the template living at /etc/nixos so you can simply sudo nixos-rebuild switch from anywhere on the system, but it is not required.
So my question is, how would this work? Should I place contents of devos/* in /etc/nixos/, or should I add the devos folder to /etc/nixos/devos and refernce it somehow from /etc/nixos/configuration.nix?
Btw, thanks for awesome work on Devos, I love it!

| b12f | Ive got my repository at `~/Workspace/os` and then symlink the directory to /etc/nixos | 21:50:04 |
| b12f | Works really well | 21:50:09 |
| genadij.udarov | So rm -rf /etc/nixos && ln -s /some/where /etc/nixos, right? Thanks for a quick reply! | 21:51:13 |
| David Arnold (blaggacao) | genadij.udarov the not-so-irrelevant difference between devos and "traditional" nixos is that devos uses flakes. Flakes are repositories. Repositories live in two places: remote & your local checkout. | 22:17:54 |
| David Arnold (blaggacao) | Where you choose to place a local checkout doesn't matter at all. | 22:18:11 |
| David Arnold (blaggacao) | ~/Workspace/devos is good. Or just ~/devos. | 22:18:46 |
| David Arnold (blaggacao) | I organize my local checkputs like so:
~/src/github.com/blaggacao/...
| 22:19:11 |
| David Arnold (blaggacao) | I use ghq for that, but since recently there is a tool called gst (ghost) in nixpkgs that does the same but a little better still (havn't had the chance to switch, yet). | 22:20:06 |
| David Arnold (blaggacao) | How does the devos repo know to which host to deploy to, you might ask. | 22:20:48 |
| David Arnold (blaggacao) | deploy-rs does it via the IP of that host. | 22:21:05 |
| David Arnold (blaggacao) | (& ssh) | 22:21:16 |
| genadij.udarov | Makes sense. My main confusion was how to run nixos-rebuild switch from any dir (which was mentioned in the docs I've linked) | 22:21:51 |
| David Arnold (blaggacao) | Oh, you'd be able to run bud ... (ask bud --help). | 22:23:10 |
| David Arnold (blaggacao) | (within the devshell of that repo) | 22:23:20 |
| David Arnold (blaggacao) | Currently those are "smart" wrappers. Unfortunately, they are not yet ported to deploy-rs to have the benefit of a unified and easy to maintain /explain codepath. | 22:24:08 |
| genadij.udarov | Yeah, I'm able to run that.
Is the statement It is convenient to have the template living at /etc/nixos so you can simply sudo nixos-rebuild switch from anywhere on the system, but it is not required. outdated? | 22:24:31 |
| David Arnold (blaggacao) | Yes! Definitly! Please do your first PR 😆 | 22:25:07 |
| genadij.udarov | Removing that line would be enough, right? | 22:25:42 |
| David Arnold (blaggacao) | Yep, I'd say so. | 22:26:06 |
| genadij.udarov | Here's a PR: https://github.com/divnix/devos/pull/393
I hope to extend the docs and/or code once I'll get familiar with the system. One thing in particular, which was PITA, was that running bud with wrong args doesn't print any error. | 22:40:23 |

| @teutat3s:pub.solar | I think I've come across the nixos-option garbage collector bug (that should be fixed in devos but we didn't downstream the fix up until now) | 00:15:05 |
