depinit is a program for managing services, some of which can be provided by
daemons. depctl sends commands to depinit. These commands can start a daemon
(and everything that it depends on), stop a daemon (and everything that depends
on it), stop everything that a daemon explicitly depends on, print the status
of a daemon or output the full state of depinit.
depinit can be run as a replacement for init, in which case its pid will be 1.
By default, depctl talks to pid 1, but it can talk to a different pid in case
depinit is running in test mode. The correct fifo can normally be found from
the pid, but if depinit is run from gdb, the fifo must be given explicitly.
The idea for this program came from simpleinit by Peter Orbaek, Werner
Almesberger, Richard Gooch and Matthias Benkmann. Thanks also Dr D. J.
Bernstein. His software is like lego for the internet, just as much fun
to play with, and makes this program usable.
