  1. Only mount vmsnap checkpoints 

    CloudAPI offers a method of managing zfs snapshots. These are prefixed with vmsnap, and are mounted on zone boot via lofs into /checkpoints

However currently, the zone boot code mounts all snapshots via lofs into /checkpoints. This presents issues for snapshots created/deleted in the global zone, that we perhaps don't want automounted or exposed to customers. For example in our use-case, backup snapshots. The main issue here is with snapshot deletion.

By simply mounting vmsnap snapshots only, we avoid this issue whilst retaining compatibility with Triton's CloudAPI snapshot functionality.
