I dimly recall that there was a little-documented utility /etc/unlink
which did just that; it was probably not on all systems, but was on our
CCI Power 6/32.
I only discovered their incompetence at the next reboot, when I had to
clean up all the orphaned (but temporary) files that were left behind
because [idn]check went berserk (we didn't have fsck back then).
