disko: first unmount and destroy all filesystems on the disks we want to format, then run the create and mount mode
|
|
* -f, --flake uri
|
|
fetch the disko config relative to this flake's root
|
|
* --arg name value
|
|
pass value to nix-build. can be used to set disk-names for example
|
|
* --argstr name value
|
|
pass value to nix-build as string
|
|
* --root-mountpoint /mnt
|
|
where to mount the device tree
