Comment 2 for bug 1929184

After all it's possible and without causing bigger headaches to have the kernel adjustments in, but not the related systemd patches.

But in such a case some explanatory words are recommended like:
"Interface names for RoCE Express adapters (shared memory communication) change to eno<UID> for UIDs <= 16K, provided unique UIDs are enabled."

This can then be added to the 21.10 release notes.

For 22.04 - which presumably has a systemd version of >= 249 - this would finally apply for all UIDs.
