Hi Peter,

Thanks for chiming in.

I guess this is a matter of taste. I have automated deployments using
daemontools and found it to integrate quite well with tools like Puppet.

Apache and rsync can now run under it because I argued for it with patches.

But I agree with you otherwise. It doesn't have to be daemontools as long
as there's something which covers most of its functionality, including the
run/finish script stuff, and not having to deal with pidfiles.
