After performing `do-release-upgrade` from 20.04 to 22.04.01, the system
failed to boot with a message of:
Failed to mount /home
Dependency failed for Local File Systems.
It took some work to figure out, but adding "nofail" to the fstab line
allowed boot to proceed, and with that, the system appears to be working
without issue.
Both /boot and /home are mounted from subvolumes on the same btrfs
filesystem. The working fstab is below:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
