[[meta title="revoke-hostname function revokes wrong hostname user ID"]]
It appears that the monkeysphere-server revoke-hostname function will
occasionaly revoke the wrong hostname. I say occasionally, but it
seems to be doing it pretty consistently for me at the moment:
servo:~ 0$ sudo monkeysphere-server n- servo.finestructure.net
The following host key user ID will be revoked:
ssh://servo.finestructure.net
Are you sure you would like to revoke this user ID? (y/N) y

NOTE: User ID revoked, but revokation not published.
Run 'monkeysphere-server publish-key' to publish the revocation.

Clearly this is unacceptable. gpg does not let you can't specify a
uid to revoke from the command line. The uid revokation can only be
done through edit-key. We do edit-key scripting in other contexts,
but to revoke a user id you have to specify the uid by "number". We
currently try to guess the number from the ordering of the output of
list-key. However, this output does not appear to coincide with the
ordering in edit-key. I don't have a good solution or fix at the
moment. Suggestions are most welcome. It may just require some trial
and error with edit-key to come up with something workable.
This underlines the problem that gpg is currently not very well suited
for manipulating gpg keyrings non-interactively. It's possible that I
just haven't figured out how to do it yet, but it's not very clear if
it is possible. It would be nice to have some alternate tools to use.
