I hate to revive a dead thread, but I don't think we came to a decision on this. Someone recently pointed out to me the existence of useradd -r and groupadd -r (they're Red Hat added functionality). When used, these commands create the first available UID and GID below UID_MAX and GID_MAX, as defined in /etc/login.defs. This seems to be doing roughly the same thing as fedora-usermgt. Does this seem like an acceptable way to create system user/groups in %post? ~spot -- Tom "spot" Callaway: Red Hat Senior Sales Engineer || GPG ID: 93054260 Fedora Extras Steering Committee Member (RPM Standards and Practices) Aurora Linux Project Leader: http://auroralinux.org Lemurs, llamas, and sparcs, oh my! -- Fedora-packaging mailing list Fedora-packaging@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-packaging
