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.
And here it is in code brackets:

Am in the middle of constructing a test setup of Nagios 4 on openSUSE 13.1 ahead of my retool of the works system on 3.2.3 under openSUSE 11.4. As has been mentioned above, the /etc/init.d/nagios file that is generated fails miserably but I found this post, which was a start. The two problems I have with is are that I have no "daemon" command available and I have no "status_of_proc" command available. The latter of these isn't so much of a bother as it doesn't appear to affect the running of the Nagios daemon once you can.
The change I made, however, to actually get it started was to whip out the "daemon" command at line 82 and replace it with
- Code: Select all
startproc -u $user -- $exec -d $config
The result is a running daemon but you get the error "./nagios: line 120: status_of_proc: command not found". Any ideas?
