I just looked to the system where I did the install, and saw that for
those files, tar (pax, actually) chose the "correct" UID and GID, not
So IMHO if those UIDs or GIDs were in use by another user or group, I
would end with a system with setgid binaries owned by a group different
that intended. If I chose a random UID/GID whwn creating those
special users and groups, I would end with files owned by nonexistent
users or groups. Is this correct?
(I know the "official" way to upgrade is to use sysinst, but don't see how
it would helped, if sysinst just calls postinstall.)
The files in question are:
