There was a change made by me in https://code.launchpad.net/~philroche/livecd-rootfs/+git/livecd-rootfs/+merge/466388
as part of LP: #2066905 to remove references to LXD in the unminimize scripts
but I also removed the calls to `unminimize` in error.
This still needs to run but without any references to LXD which no longer
needs to be `unminimized` via snap installation.
