if ! blkid "${config.device}" >&2; then
sgdisk --clear "${config.device}"
fi
I can't tell if I found a bug or if I'm just not understanding this; blkid exits with code 2 when run on a blank (all 00) block device, in which case it... clears the gpt label? that isn't there? | 21:55:56 |

Okay, right now I’ve gotten it to error on the build with:
"Unable to read fragment cache entry"
"Unable to read page"
"unknown filesystem type 'btrfs'" what exactly are you building? Do you mean nixos-rebuild build? Could send the full output in a pastebin or smth? | 22:03:21 |
| shelvacu | In reply to @pink_rocky:tchncs.de
configuration.nix Separately, I highly recommend switching to a flake-based config in a git repo. That would make it possible to link to a specific commit and then everyone else can run the exact same build. | 22:05:09 |
| shelvacu | Also I strongly recommend not using /dev/sdb as the device; the ordering can change between boots and when you add/remove thumb drives. Instead look for your drive in /dev/disk/by-id/ | 22:06:24 |
| shelvacu | also I can't build your config because it's missing hardware-configuration.nix | 22:09:11 |

| francesco | Hey folks, quick question: I'm trying to setup a bind mount that points to a file system part of a disk managed by disko. I am unable to build the disk image because the order of operation is wrong:
- disks and filesystems created
- (a file-system irrelevant to this issue is mounted)
- bind mount tried, but source fs not mounted
- (I assume here it would mount the source fs)
Is there anything I can do to influence the order? I tried messing around with _meta.deviceDependencies but without much success.
| 11:59:29 |
| shelvacu | you should be able to look at the script produced by disko and confirm #4 | 12:01:32 |
| 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?
