For machines you have the keys for:
# tarsnap --nuke --keyfile /path/to/machine/keys

If you've lost the keys to a machine, send me an email off-list and I can
nuke them for you.

I'm not sure what this means.  Running `tarsnap --nuke` with a particular
set of keys will delete all the data associated with those keys; it doesn't
matter what system uploaded the data in the first place.
