If all you're trying to achieve is to have a default fixed UID, but still allow for some local customization, why not something along the lines of: | %{name}_UID=${%{name}_UID:-23} | useradd -u $%{name}_UID And then the admin who wants to customize package foo can run: $ foo_UID=1012 rpm -ivh foo-1.0-1.blah.rpm or $ foo_UID=1012 yum install foo (Note that I haven't tested this...)
