Comment 28 for bug 1735839

Tested on (master at the time of writing): https://git.launchpad.net/curtin/commit/?id=7afd77faf99739cc2fe7ab0c256d2e153bccb604

LGTM

Note: see the attached domain.xml of a test machine sda (root disk) and vda do not have a serial attached. All devices except for sda were renamed in MAAS to <commissioning-dev-name>-renamed

maas <profile> machine read xeqrrw # post-deployment (successful without some serials which is expected)
