Reimage command doesn't confirm that reimaging has happened

[telyn]

The output is just

node3.kube will be reimaged with the following. Note that this will wipe all data on the main disc:

Image: jessie
5 public keys: telyn lonsdaelite 2015, gitlab-ci, telyn@zirconia, telyn@boehmite, telyn@eboracum
Root/Administrator password: tkWTrkxDPDWPhuJmAre you certain you wish to continue? (y/N) y

and a zero exit code to say it went okay.

Something like "Reimaging successfully requested" or such would be better
