@brian:bmcgee.ie	yeah, so I missed the eval warnings. Turns out it just wasn't mounting things which is why it appeared to 'work'. Back to the drawing board.	14:00:50

guiniol	Hi all! I am trying to use disko to setup a ZFS pool, and it seems that the code creating the partitions is not giving them the partlabels that the code that's creating the pool expects:	22:06:11

guiniol	What am I doing wrong? I checked the `members` in my vdevs are indeed the right disks	22:06:56
guiniol	I couldn't quite find the part that creates the partlabels (the part that expects them is here: https://github.com/nix-community/disko/blob/84a5b93637cc16cbfcc61b6e1684d626df61eb21/lib/types/zpool.nix#L238C1-L238C109)	22:08:37

guiniol	so, my names were too long and hashed instead of used as is, except no one told the code in zpool.nix	22:19:47
guiniol	I'll open an issue	22:19:52
guiniol	turns out there's one already: https://github.com/nix-community/disko/issues/913	22:22:09

bl1nk	I replaced the OS on a VPS with NixOS using NixOS anywhere, that used disko as well. I now want to replace the generic first time install with something custom using colmena. Do I copy the disk-config.nix over to that configuration.nix as well and add the disko module?	14:39:53

bl1nk	Previously I used nixos-infect which also generated `fileSystems.*`, I guess I'll have to write that myself now?	15:20:37
bl1nk	Ah, reading the docs helps :) https://github.com/nix-community/disko/blob/master/docs/quickstart.md#step-7-complete-the-nixos-installation	15:24:38
	@kranzes:matrix.org left the room.	15:29:36
phaer	If you do, you are able to use the fileSystems disko creates for your from your disko config. That's about the only difference, disko won't run again or so by including it into your config	22:57:31

bl1nk	In reply to @phaer:matrix.org If you do, you are able to use the fileSystems disko creates for your from your disko config. That's about the only difference, disko won't run again or so by including it into your config I went and ran `nixos-generate-config` on the host to get back a hardware-configuration.nix with `fileSystems.*` defined if that's what you mean?	12:53:34
lassulus	yeah, those usually conflict with disko, you can run nixos-generate-config with --no-filesystems	13:12:28
