Beauty is in the eye of the beholder.  I have never found this
particular man page to be bad enough not to consult when needed, even
for the first time (like I did, lo these many eons ago, when it was
even harder to read than now) and the effort pays off big time in
future uses.

I could have just said RTFM in so many letters, but I /was/ trying to
be nice(r).

That should work, too, if you know how to use it (I'm not too fond of
the man page for this one, either).

Actually, the "-type f" is not needed, unless a system has enitities
on it that are not files but masquerade as them with names like

The problem Lanny cited was that the packages were installed but the
kernel did not appear in /boot, and the suggested solution was to
remove them and then reinstall them.  Yes, if they are properly
installed, you don't need to know where they are.  Yes, you do not
need to know where they are to remove them (your previous email this
subject).  But you're going to have a real problem reinstalling them
if you don't know where they are.  Hence, the "find" suggestion.

'Find' is your friend.
