I fix this in the release tarballs I roll (for WU-FTPD, not Apache) by
rolling them _as_ root (dunno, never looked to see if tar has an option
for clearing the UID/GID in the tarball).  That way when un-tar'd by root
the UID and GID are root and when by anyone else they're the user's.  I
consider that a policy of 'least surprise'.  It always bothers me when, as
root, I un-tar a package and the files end up owned by some UID/GID which
doesn't even exist on my system or, worse yet, owned by one of my

Fixing this at install time is a fine backstop (yes, set the GID to 0) but
it should be fixed in the 'howto release'.
