Correct on creating the file and its function, but I would *never* use a
'reboot' command without using 'sync;sync;sync;reboot'. "reboot" does
not flush buffers, so if you fail to use the sync in that line, data in
the buffers may not be written to disk and filesystem or data corruption
may occur. It _has_ happened.
Using the 'shutdown' command handles all that for you with both the file
creation and the clean reboot. Thus the suggestions to use "shutdown
-Fr now" as the best way to do a forced fsck on reboot.
