Comment 90 for bug 1834875

a.) I gave the wrong link. ugh. It should have been:
  https://code.launchpad.net/~smoser/cloud-initramfs-tools/+git/cloud-initramfs-tools/+merge/379774

b.) the fixed link to 'a' probably makes more sense now. But basically
you need a newer cloud-initramfs-tools to adjust for the fact that
growpart needs flock now.

cloud-initramfs-tools I believe is still a "native package". So it just
has the packaging along side

c.) you can use new-upstream-snapshot. cloud-utils is set to use the
same basic workflow as cloud-init or curtin.

I'm OK to upload cloud-initramfs-tools and also cloud-utils, but I think
in both cases it makes sense to get someone from server team to do it.
Just to have someone other than myself having done it.
