Description of problem:
the rpm package creates rpm user using 
/usr/sbin/groupadd -g 37 rpm > /dev/null 2>&1
/usr/sbin/useradd  -r -d /var/lib/rpm -u 37 -g 37 rpm > /dev/null 2>&1
but there is no prereq on shadow-utils which contains /usr/sbin/groupadd and
/usr/sbin/useradd. Also, the "dev" package containing /dev/null is not prereq'ed.


Version-Release number of selected component (if applicable):
standard redhat-8.0

How reproducible:
install a chrooted redhat-8.0 and install rpm-4.1 before installing
shadow-utils. No dependency problem is reported, but the rpm user can't be created.


    
Actual results:

Additional info:
chrooted installs are not important for Joe Average Home User, but are very
important when doing large scale installs. Having correct prereqs is necessary
for those installs (and would help Red Hat during the making of new versions, I
guess).
