While %postun is running do you have any context of the rpm command line
options?

I have built an RPM that during installation needs to add an entry to
/etc/passwd and /etc/group. This is easy to do using the %pre section:
%pre
egrep -q "^njeanon" /etc/group; \
if [ $? != 0 ]; then \
groupadd nje 2>/dev/null; \
groupadd njeanon 2>/dev/null; \
useradd njeanon -g njeanon; \
fi
Similarly, when the RPM is being uninstalled I need to get rid of those
entries. Again, easily done with %postun:
%postun
rm -rf %{nobodyhome}
userdel njeanon 2>/dev/null
groupdel njeanon 2>/dev/null
groupdel nje 2>/dev/null
However, if I am upgrading using -Uhv then I get the %pre and %postun
sections run as part of the upgrade. This means that the work done in %pre
gets undone by %postun. If I was simply doing a rpm --erase I would be
satisfied but doing -U then this is not what I want.
So my question is, how do I prevent -Uhv undoing the %pre work (to be
pedantique if it's doing an upgrade then the groupadds aren't issued because
the check tells me the entries are already there).
