Restart daemon after config change

[Kief Morris]

Hi folks,

I'm using cfengine 2.1.0b5.

I want to find a way to restart daemons when their configuration files
have been changed. I thought I might use file checksum monitoring
to set a class (eg. "bind_needs_restart") that would later trigger
a shellcommand to run the init script ("/etc/init.d/bind9 reload").

However, the define attribute isn't triggered when the checksum
changes, so that's a no-go.

Does anybody else have a good way to do this?

Thanks,
Kief
