Hmmm. But why does it still happen? :-///

My versions:
glibc-2.3.5-6
nscd-2.3.5-6
shadow-utils-4.0.7-7

Example:
rpm -Uvh test-0.1-1.i386.rpm
Preparing...                ###########################################
[100%]
   1:test                   warning: group test does not exist - using
root3%)
########################################### [100%]
warning: group test does not exist - using root

rpm -qp --scripts test-0.1-1.i386.rpm
preinstall scriptlet (using /bin/sh):
groupadd -r test >/dev/null 2>&1
postuninstall scriptlet (using /bin/sh):
groupdel test >/dev/null 2>&1

I'm posting this to the above mentioned bugs as well...

Thanks a lot,
 Oliver
