SSH host key maintenance, local provider

[Stuart Bishop]

Hi. Has anyone got a simple mechanism for keeping their
~/.ssh/known_hosts and ~root/.ssh/known_hosts files clear of ephemeral
juju machines?

I did have a script that cleared it out on bootstrap, but it has
stopped working and I thought I'd ask here for current best practice
before debugging it.
