Shouldn't be to hard. Implementing dependecies was the hard part,
implementing a "use" functionality simply means to shuffle the
servicelist so services are started in the prefeered order. Okay, maybe
some graph theory but not much. I'll put myself up as responsible for
this function since I like to fool around with lists/graphs and
pointers =8-o
(2) Interesting but too dangerous. Breaks the concept of having a
validation loop. Then we would have signal based tests and a
validation
loop. The signal based code might break with the multitreaded code.
And
it breaks with the "unix" idea one small tool for each task. I think
init
is there where its supposed to be. I think we would not get past a
proof
of concept and wouldn't achieve anything a user would adept. Just my
two
cents.
a) I agree with your concerns, this is not trivial stuff. However, I
suggest we put it on our TODO list
(http://www.tildeslash.com/monit/next.html) but with a low priority. If
we managed to implement this (or maybe as a better hack than using
signals) it would be a very good feature, so monit does not need to
depend on pid-files only.
b) init is absolutely where it's supposed to be. monit will not replace
init, but can replace execution of SYS V rc startup scripts. The setup
will look something like: init -> monit -> start-system-daemons. See
Igor's general setup (which is not far from a sysinit replacement) here
