Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
passwd rpm depends on pam, which in turn depends on cracklib and cracklib-dicts. I do not want to dispute the need for strong passwords but sometimes this measure is not necessary. For example, containers are often without any passwords - regular users are not supposed to ever log in. Cracklib-dicts take a lot of space in container images. It would be great to have a way to install a minimal system without cracklib-dicts.
passwd links to libpam, so it will always depend on PAM. Whether pam, libpwquality, or whatever puts pam_pwquality into default PAM configs should depend on cracklib-dicts is up to whatever owns the default configuration.
(I could imagine a RPM packaging where the user can choose between a PAM configuration which allows password login and requires cracklib-dicts, and a configuration where password login is universally prohibited and cracklib-dicts is unnecessary.
But, honestly, my first instinct is to just close as WONTFIX; one of the supposed benefits of Docker images is inheritance. Sure, by naive accounting it adds 9M per a Docker image, but really that is only 9M per a Fedora base image shared across a big set of Docker images. That, more or less one cracklib-dicts instance per a major OS version should not hurt AT ALL.)
