I'll file this as a bug against juju-core...

Fwiw, I really don't think charms should be running things directly out of the charm directory (such as nagios checks). In this case it should be copied to /usr/local/nagios/plugins as part of the charm.

And it seems https://bugs.launchpad.net/juju-core/+bug/1205286 confirms charms shouldn't be doing this either.
