As Warren says, you don't want to sync after an fsck run has made
changes to the disk. Simply turn off and reboot. One gotcha Warren
omitted was the process /etc/update, which is usually started at
boot-time from /etc/rc. This process does a sync every 30 secs
automatically.  Before fscking a live filesystem, kill update first!
If fsck finds anything wrong, shutdown immediately without a sync.

Of course, fscking unmounted filesystems is far safer, but not always
possible for the root partition ...
