Hi Rob,
First thank for your quick answer.
Then I've tried those commands you gave me. It's seem to be good, but not what I really want to do.
I'triing to explain more :
I'm making a specs file to create rpm package from a source tar.gz in /usr/src/redhat/SOURCES/. The thing a would like to make is to add an user/group directly in the rpm file and not during the compilation and creation of the package.
The package I created is not a src.rpm but i386.rpm so from a basic system I would like the user/group will be create in the binary rpm and directly add with the command rpm -ivh .... Is it possible ? or is it the command you gave me but I put them in wrong place. Is it in %prep, %build ...%install ?
Do you see what I mean ?
