 Arian | Is Dev/vda3 mounted at this point? | 09:27:35 |
 @elvishjerricco:matrix.org | no | 09:27:41 |
| Arian | Maybe you only get these events for unmounted partitions | 09:27:59 |
| @elvishjerricco:matrix.org | well that would still be the case in stage 2 | 09:28:25 |
| @elvishjerricco:matrix.org | for any non-root partitions | 09:28:28 |
| Arian | That would explain why it doesn mess with the root fs. But it would indeed screw things up for anything else in fstab | 09:28:34 |
| @elvishjerricco:matrix.org | I think I'm going to take my eyes off this problem for a bit and get some sleep. Arian Do you have any interest in taking a glance at my test config in the meantime? | 09:30:29 |
| @elvishjerricco:matrix.org | (it's using my fancy "installer-small" nixos test setup that makes installer tests way way more efficient) | 09:30:58 |
| Arian | Yah send a link. I might have a look later | 09:32:01 |
| Arian | Though I'm gonna do some touristic stuff with @flokli:matrix.org first | 09:32:13 |

The last commit probably breaks all the other ones so if you're interested in the installer-small stuff check out the one before it. But the last one contains the repart test case

 @srestegosaurio:tchncs.de | If I assign a non-existent slice to a service, will it be created with default values or return an error? | 02:42:45 |
| Arian | I dont remember | 09:22:13 |
| Arian | Try it out? | 09:22:20 |
 antifuchs | soooo how long is scripted initrd going to be a thing? I have a truly annoying (semi-guaranteed to be racy) nixos test for scripted, and would love to get rid of it someday | 23:39:24 |
| @elvishjerricco:matrix.org | I have not made as much time as I usually do for nixos stuff since 24.11, so systemd by default in 25.05 is unlikely, again :( | 23:44:41 |
| @elvishjerricco:matrix.org | plus I've been sidetracked by a couple other nixos things like the ISO | 23:45:08 |
| antifuchs | understandable yet sad | 23:45:13 |
| antifuchs | no worries, I'm gonna figure this out one way or the other | 23:45:24 |
| antifuchs | can you think of a good way to halt the boot process in scripted initrd until a condition is met? I have been trying
boot.initrd.preLVMCommands = ''
while ! [ -f /tmp/fnord ] ; do
sleep 1
done
'';
and it sure seems to stop the boot but you don't get output from the machine in case anything goes wrong...
| 23:46:42 |
| @elvishjerricco:matrix.org | yea that's, uh... a good use case for systemd initrd :P | 23:48:41 |
 uep | random idle musing: what's the right way to express dependencies between services, that says service A needs to be running, but should also be restarted whenever service B starts or stops?
Use case:
- Service A: smartd, which either doesn't notice new disks arriving, or gets very upsetti when they go offline
- Service B: something that's going to power on/off and zpool import an external chassis with 36 disks in a backup pool, to be triggered by other conditions

| uep | (B might get split into separate power state and import state units, but that's not really important for this question. I want to restart smartd around the disks either arriving or leaving | 23:52:17 |

| @elvishjerricco:matrix.org | uep: I wonder if that's more of a job for udev | 23:54:36 |
| @elvishjerricco:matrix.org | * uep: I wonder if that's more of a job for udev rules | 23:54:49 |
| uep | maybe | 23:54:51 |
| uep | it might also just be better smartd configuration | 23:55:00 |
