 @jkarlson:kapsi.fi | hibernation is a nightmare | 07:18:05 |
| @jkarlson:kapsi.fi | filesytems should really be used with nfs or something with hibernation | 07:18:53 |
| @elvishjerricco:matrix.org | Emil Thorsøe: hm? Why nfs? | 07:19:43 |
| @jkarlson:kapsi.fi | it decouples the processes from internal filesystem state | 07:20:03 |
| @jkarlson:kapsi.fi | so filesystem could be effectively unmounted in any way that could cause corruption | 07:20:40 |
| @jkarlson:kapsi.fi | note that such code is not really implemented, maybe autofs | 07:20:57 |
| @jkarlson:kapsi.fi | I guess filesystemd could be written in a way that adds a nfs wrapper or libc | 07:26:34 |

 @lily:lily.flowers | Is systemd-initrd not working with installer ISOs a known problem? It seems that they set root= on the kernel cmdline to the device label which contains the squashfs, but that doesn't play well with the tmpfs / filesystem defined in the fstab (and the fstab entry ends up getting ignored in favor of the cmdline root=, which is obviously wrong in this case) | 03:02:21 |
| @lily:lily.flowers | (to be clear, the NixOS installer tests pass fine in the test framework, but those don't have to do the ISO trickery) | 03:02:53 |
| @elvishjerricco:matrix.org | Yea that's known but not well explored. | 03:02:59 |
| @elvishjerricco:matrix.org | We've known the isos don't work all along but I don't think anyone's really investigated it | 03:03:17 |
| @lily:lily.flowers | Hmm, I may look for a solution at some point then | 03:03:36 |
| @elvishjerricco:matrix.org | That would be wonderful | 03:03:45 |
| @lily:lily.flowers | I'm not sure if that'll be changing the cmdline or if it'll be doing some hackery with systemd (but I imagine it'll be the first one -- we really shouldn't be setting root= with that for systemd-initrd) | 03:04:12 |
| @lily:lily.flowers | Is there an open issue in nixpkgs for it already? | 03:04:18 |
| @elvishjerricco:matrix.org | I don't think so? Check the systemd stage 1 GitHub project in the repo | 03:04:48 |
| @elvishjerricco:matrix.org | There's probably a correct way to use the root= cmdline, but it probably involves making NixOS use that parameter correctly in the first place (which I have a patch for on a branch somewhere) | 03:05:49 |
| @lily:lily.flowers | I really don't think the installer should be setting it for where to find the squashfs, given it's not an actual root fs. But I'll have to look at how the old stage-1 is handling that before determining the best method | 03:07:30 |
| @elvishjerricco:matrix.org | Ah that's a fair point | 03:07:59 |
| @elvishjerricco:matrix.org | Maybe check how fedora's ISO works? I believe fedora has used systemd in stage 1 for a few years now. No idea about their ISO though | 03:08:33 |
| @lily:lily.flowers | In reply to @elvishjerricco:matrix.org
Maybe check how fedora's ISO works? I believe fedora has used systemd in stage 1 for a few years now. No idea about their ISO though Actually it looks like other distros set root=live:CDLABEL=. So maybe that has special handling | 03:10:33 |

| @elvishjerricco:matrix.org | Yea check fstab-generator for that | 03:10:50 |
| @lily:lily.flowers | Either way, just thought I'd ask here if it was a known issue. I'm about to log off for the night | 03:10:56 |
| @elvishjerricco:matrix.org | * Yea check fstab-generator.c for that | 03:10:58 |
| @lily:lily.flowers | In reply to @elvishjerricco:matrix.org
Yea check fstab-generator.c for that Yepp:
if (startswith(arg_root_what, "live:")) {
log_debug("Skipping root directory handling, as root on live image was requested.");
return 0;
}
