Error: [Errno 2] No such file or directory: 'udevadm': 'udevadm' This comes from: https://review.opendev.org/#/q/I9db48a3462422749290bbb887c14816734ab0478 The fix is to add systemd/system-udev into the container
I believe this has been resolve by Marc Goddard's fix - https://review.opendev.org/#/c/655688/.
Note that the requirement to use udevadm is not new, its been in ironic-lib since 2017 with this patch [1]. There doesn't seem to be any issues with x86 on rhel-8 or earlier, only with ppc, but again I believe that the patch in kolla resolves this.
