UFS is refreshingly robust (at least in my experience) in
this regard, in that you may end up with a truncated (or
slightly mauled) file but never a corrupt filesystem.

Even kicking the power cord out only results in minor,
repairable corruption something like 30% of the time.

Again, in terms of personal experience I would suggest that
umount -f is shrug-inducingly "safe" at 3 or 4 nines of the time.
