Comment 62 for bug 1861941

TODOs (currently being started):

1 - adjust/add bcache-tools patch to use bcache-super-show (full path)
    (bcache-tools - bionic | focal | groovy)

1.1 - Ubuntu kernel patches for CACHED UUID resubmission could be removed
      (linux - bionic | focal | groovy) IF (1) is done and SRU'ed

1.2 - Work with upstream so they merge @raharper's patch

2 - drop systemd patch for /dev/disk/by-uuid | /dev/bcache/by-uuid ??
    (systemd - bionic | focal | groovy)
    - I prefer to keep this patch and open upstream discussion for (3)

3 - blkid should not report FS_UUID for bcache backing devices (not a filesytem)
   (blkid - bionic | focal | groovy)
   - would avoid useless dev/disk/by-uuid, just like the systemd patch
   - blkid would have to be SRUed to all or systemd patch kept
   - will drive upstream discussion

4 - provide a temporary PPA with all fixes before SRU happens (MAAS tests)
