 shelvacu | which would be good to check since its a very different issue if its mounted nowhere | 12:02:08 |
 francesco | Thanks let me check that. | 12:03:07 |
| francesco | My assumption was correct: the issue starts here: https://github.com/nix-community/disko/blob/17d08c65c241b1d65b3ddf79e3fac1ddc870b0f6/lib/default.nix#L970
Basically I have root (tmpfs), a writable partition at /system, and a bind mount /nix -> /system/nix. | 12:06:37 |
| francesco | the mount order is currently:
- root
- /nix (bind)
- /system/nix
I guess a possible work-around would be to call system anything that is lexicographically before nix?

Basically I have root (tmpfs), a writable partition at /system, and a bind mount /nix -> /system/nix. im not super familiar with disko but it seems youve found proof that mount ordering simply isnt implemented (other than /a before /a/b because alphabetical) | 12:09:44 |
| shelvacu | if its any help, once disko configures fileSystems.* in a nixos config it should all just work | 12:10:41 |
| francesco | I'm wondering if it would make sense to implement fileSystem.<name>.depends also from within disko? By doing so, disko can use this information for ordering, as well as populate the entry in nixos. Alternatively, adapt disko to do something similar to what nixos does without extra config (figure out fs dependencies automatically, by looking at their mountpoints) | 12:12:52 |
| shelvacu | that would be neat imo | 12:13:31 |
| francesco | I just opened two PRs about the above:
- https://github.com/nix-community/disko/pull/1056
- https://github.com/nix-community/disko/pull/1057

| Fynn | Hi! I'm currently trying to set up a machine with encrypted ZFS on root following the example:
https://github.com/nix-community/disko/blob/master/example/zfs-encrypted-root.nix
Now I am a bit confused on how I can set the encryption passphrase, since I am not prompted during the disko run. There is keylocation commented out in the file, can I use the for the nixos installer and switch to the prompt afterward? | 16:35:33 |
| Fynn | Alright turns out it does prompt, but to encrypt the pool I have to use rootFsOptions instead of options :) | 16:49:47 |

Alright turns out it does prompt, but to encrypt the pool I have to use rootFsOptions instead of options :) im surprised it doesn't error the other way around. it should tell you encryption is an invalid pool option, or similar | 04:20:47 |
| Fynn | I only saw, that it was not able to mount the datasets. When I changed the keylocation to a file, it said that it was an invalid option. Could be that I overlooked it on the first run though. | 07:39:52 |
 @musicmatze:beyermatthi.as | Is Disko able to add to my existing zfs datasets? | 18:16:57 |
| @musicmatze:beyermatthi.as | So if I create a new dataset in the config, will it generate it upon nixos-rebuild? | 18:17:19 |
 Sandro 🐧 | I don't think so | 18:25:38 |
| Sandro 🐧 | at least I have been always manually reconciling that | 18:25:43 |
