OK, So I'm trying to finish bringing my development environment up to FC2. I have several packages I need (mach being one of them) that attempt to install new users and groups for themselves in their %pre scripts. This used to work fine, but now installing them I get lots of "warning: group mach does not exist - using root" spam. Usually upon checking /etc/passwd and /etc/group, the new user/group have been created, but for some reason there is a lag between the useradd command the new users subsequent availability to the system. I'm running LDAP auth, and I have already tried turning off nscd which didn't help. I believe this to be the same problem reported at http://www.redhat.com/archives/fedora-list/2004-July/msg05419.html but there was no resolution there, and a cursory search of bugzilla isn't getting me anywhere. I either need a workaround for this on my local machine (how did it "break" anyway?) or a way to fix the useradd commands in my rpm scripts so they block until the new user is available. Inserting a sleep 5 didn't seem to do the trick, either. FYI, the current command line looks like this: /usr/sbin/useradd -g mach -c "mach user" \ -r -m mach -d %{_localstatedir}/lib/mach > /dev/null 2>&1 || : RFE: rpm should have a %createuser and %creategroup directives that handle this sort of stuff. They should have flags to remove (or not) on uninstall, etc. Thanks. --erik
