Heh, no problem.  I had hoped the post itself would be sufficient to
pose a question.  The question ultimately was: why does launchd not
automatically start my new service?  (The fact that the service is
amanda is rather tangential by now.)

The backup server is NetBSD, the OS X is just one of the machines that
are being backed up.  The way amanda works, you need to have the amanda
client running on each of the machines you want to backup, so the amanda
process can connect to it and start the backup.

On OS X in this case.

I used to use it stand alone, no launchd involved.  And it worked just
fine, once I manually HUPped xinetd, but the problem was that it
wouldn't automatically be launched at boot time, so I tried to give
launchd a shot.

Yupp, read all those.

As best as I can tell, it seems to be a load-order issue.  But then
again, that's supposedly one of the things about launchd:  you don't
really get a decent launch order.  I don't even know in what order it
tries to start the services.

I thought it might start them in alphabetical order, so I renamed the
service to 'z-amanda.plist', so it would be started last.  However, that
didn't work.  It still was started before some other services at boot
time and didn't work.
