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.

Fixed In Version: rhel-system-roles-1.4.0-1.el8
Doc Type: Bug Fix
Doc Text:
.Role tasks no longer change when running the same output Previously, several of the role tasks would report as `CHANGED` when running the same input once again, even if there were no changes. Consequently, the role was not acting idempotent. To fix the issue, perform the following actions: * Check if configuration variables change before applying them. You can use the option `--check` for this verification. * Do not add a `Last Modified: $date` header to the configuration file. As a result, the role tasks are idempotent.

Description Rich Megginson 2021-05-13 18:07:03 UTC 
Description of problem:
The postfix role is not idempotent.  If you run the role one day, then run the role another day, the config file is updated in the step "Add header 1 to configuration file" which adds the "# Last Modified: $date" to the config file, because it uses the date.

It is bad practice to use a "# Last Modified: $date" header for this reason.  The role should omit this header.
