I believe you're missing the point that we don't just cleanup old
entropy file -- we re-generate it via "/etc/rc.d/random fastsaveseed" call in
postrandom_start()

That's how "/etc/rc.d/random fastsaveseed" translates in to "/etc/rc.d/random
stop", which does the jobs of re-generating seed file.

In the end, assuming machine boots up passed postrandom script, we're left with
no stale seed files, but a freshly generated ${entropy_file_confirmed}, which
should be sufficient to seed next bootup.

Thanks
