If the file was truncated, mike was referring to using restore(8) with
-m. In other words, setting up the good old "you _do_ keep backups,
don't you?" line :-)

If the file was removed and recreated, there's no guarantee that the
inode it uses will be the same as the old one.

If the file was (say) a log file that some process still has open (but
is no longer linked into any directory) you could probably use fsdb
(followed by a fsck) to recreate a link to the file.
