Description of problem:
While updating selinux-policy-targeted package the following shows up:
libsemanage.add_user: user system_u not in password file
A check of the package scripts reveals that that message is a result of running:
/usr/sbin/semodule -B -n -s targeted;
User 'system_u' is indeed absent from /etc/passwd. Should be there?
Version-Release number of selected component (if applicable):
On this test system selinux is actually disabled.
