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.

Current discussion around https://issues.redhat.com/browse/OCPBUGS-10787 is leaning to shipping at least PoC code in nmstate.

Something of the form:

nmstatectl pin-nic-names 

Possibly with options like --active-only (or --ignore-inactive) or `--include-only-glob=enp*` etc.

Filing this to track work on this from the nmstate side.

Patch send to upstream: https://github.com/nmstate/nmstate/pull/2306

The whole workflow:

 * Use `nmstatectl persist-nic-names` to pin __every__ ethernet interface to its
   MAC via systemd .link file.
 * After boot into new environment, `nmstatectl persist-nic-names --cleanup`
   will remove un-required systemd .link file.

Key tech point:

    Use `udevadm test-builtin net_id /sys/class/net/<iface_name>` to check
    systemd preferred interface name and compare to current interface
    name.

Tested:
 * CentOS stream 9 VM by renaming a existing interface to new name.

 * RHEL 8.8 and CentOS stream 9 on Mellanox MT27710:
    * Not from upgrade, just reinstall CentOS stream 9 and restored the
      nmstate created .link files.
