Steps to reproduce:
(assuming bootstrapped precise)
export JUJU_REPOSITORY=/usr/share/doc/juju/examples
juju deploy local:mysql
juju deploy cs:~clint-fewbar/oneiric/munin-node
juju deploy munin
juju add-relation mysql munin-node
juju add-relation munin-node:munin munin
juju destroy-service mysql
juju destroy-service munin-node
Debug log will show the traceback and the old unit agent will be left running on the machine. Given the lack of cleanup I understand that the best way is to terminate the machine, but I'd like to see these agents at least get gracefully removed from the machine in case I just want to re-deploy the same thing to it.
