Maybe not a good assumption afterall -- I can no longer boot using kernel 3.10.0-514 or 3.10.0-862.
boot.log shows: Dependency failed for /mnt/data Dependency failed for Local File Systems Dependency failed for Mark the need to relabel after reboot. Dependency failed for Migrate local SELinux policy changes from the old store structure to the new structure. Dependency failed for Relabel all filesystems, if necessary.
