The command: ls -Z /etc/fstab
Outputs: unconfined_u:object_r:etc_t:s0 /etc/fstab
On an unmodified fstab file. If I modify the file using 'sudoedit'
command, which uses GNU Nano on this system, preserves the same extended
file attributes. However, after using emacs -Q:
C-x C-f /sudoedit::/etc/fstab
<any file modification>
C-x C-s
The command: ls -Z /etc/fstab
Outputs: unconfined_u:object_r:user_tmp_t:s0 /etc/fstab
Which will prevent system from booting.

No further comment, so I'm closing the bug.
