The pidfiles concept per se is broken in my opinion. Pidfiles provide
unreliable information, and are subject to races. I successfully use
service daemons that don't care about pidfiles, can easily be configured
to run in a chroot, and can reliably be controlled through signals.
Such service daemons needn't care about closing possibly open file
descriptors, creating and cleaning up files in /var/run/, the current
process state, and fork and exec.
