Hi Bron,

cyr_conf sounds good :)

For the "refuse to start", do you think it should be integrated into
master or being kept in the init script?
What would be very cool is a detect feature which detects things like
database config from the configdir. That way it could also override
configuration settings from the config files on startup and log about it.
It sounds a bit dangerous, what do you think?
