There were occasions where removing the backup drive would confuse luks
and prevent re-mounting. This fixes the issue by attempting to luks
close and open the drive before mounting, thereby correcting any issues
where the drive would stick.
Occasionally, the latest snapshot in the snapshots dir would get out of
sync with the backup drive. Change the script to detect drift and fix it
before performing a backup.
Daily driver installs from pacman, yay, and snap should all share a
similar naming convention. This will be "<package
manager>_daily_drivers" from now on.
