Softupdates updates on-disk structures in the background, and
background fsck cannot relink unreferenced files into lost+found, so
you run the risk of losing both the original and backup copies of
important files in case of a sudden reboot. Imagine you edited
/etc/rc.conf, saved it, and 5 seconds later the system panic'ed.
Because the default metadata flush time is 28 seconds, there's a pretty
good chance that neither the new file or the original is in /etc after
a reboot. I got bit by this three times before I learned my lesson. I
have disable softupdates on /, and crank the softupdates delays down to
10/11/12 seconds to minimize the risk to my other filesystems. At least
there are /var/backups and /boot/kernel.old which let you recover the
really important files :)
