I'm also thinking about cloning my current setup, and upgrading without doing the make install-init command and seeing if it still works. If I get around to it in the next couple of days, I'll post my results.

It does seem to work without running the make install-init command.
Yeah, but you will run into other issues (status, runuser, etc). I will try to get Ludmil to post a copy of the init script we hacked out the other night. It is not perfect, but it does work.

Until I went to look at the Nagios web interface. it looked like the Nagios service was not running (see attachmet whoops.png)
I checked the status and got this
root@nagios downloads/nagios# /etc/init.d/nagios stop
is not running ... failed!
root@nagios downloads/nagios# /etc/init.d/nagios start
is not running ... failed!
$Starting nagios:
This time nagios was actually running and I could see my Service status
