| matthewcroughan | notice how I've just guessed the by-partlabel paths and it's not happening by nix evaluation, and how I've had to use a recursive set to get the device path | 14:24:24 |
| matthewcroughan | This also won't work in the image builder, it will only work for running the real disko script due to the dependency on the device path which will differ in the VM
