Speaking of daemonic and launchctl/launchd, can anyone say
the status of
updating daemonic to support launchd on OS X 10.4 and above?
I see feature
requests for it in both daemonic's and Fink's trackers on
Sourceforge, and
it is listed in the 'Roadmap: Medium Term Goals' on the Fink
wiki. Daemonic
really should support the preferred method of controlling
daemons (not to
mention all the other neat stuff that launchd can do),
rather than using
only a deprecated method that is likely to disappear
altogether at some
point. I'm just curious about it at this point, I'm not
currently running
any Fink-installed daemons on any of my Tiger systems.

This is one of those things that everyone agrees is
something that  
should be done but no one has actually gotten around to
doing it.  
Part of the problem is that daemonic is old and crufty C
code which  
few people really understand and upgrading to launchd
without  
breaking existing packages is very tricky. The old
StartupItems  
simply used shell scripts and therefore could do anything a
shell  
script could do. Launchd is a lot more restrictive and needs
to track  
the status of every process it's managing. For example, it's
not  
uncommon for daemons to fork a new process and then quit.
That causes  
launchd to have a nervous breakdown. 

I've played with a couple of ideas but never come up with a 

satisfactory replacement until now. It turns out that
MacPorts came  
up with a good solution involving a utility called daemondo
and some  
wrapper scripts. I'm working on a replacement daemonic
(written in  
Perl for easier maintenance) now. No promises on how long
it'll  
take. 
There's a "daemondo" package in my experimental
cvs  
directory in danielj/10.4/daemondo.info if anyone want's to
look at  
it. It'll be part of my solution. Daemondo is actually a
pretty neat  
program that will run programs in response to various system
 
notifications like network changes and wake-from-sleep in
addition to  
acting as an adapter to launchd.

Awesome! Does this mean that I finally can have 'postqueue
-f' run  
every time my notebook gets connected to the internet? That
would  
also be useful for automatically merging my elog's...

Sure. From daemondo:

The argument restart-netchange will cause the daemon to be
restarted  
when
the network configuration changes. This is a shortcut for
the more
verbose --restart-darwin-notify
com.apple.system.config.network_change.

You would have to set the restart command like:
--restart-cmd  
postqueue -f ;
See the daemondo package description for details.
