Code review comment for lp://staging/~smoser/maas-images/trunk.dyn-netconf-krd-only

The first hunk of this (cloud-initramfs-dyn-netconf added)
got fixed under revno 392 (fdebb643909b4dc8d62453ce657f2705a038b29d).

The remaining chunk is a simplification for sure. but Im' not going to push on that now.
