initial munin-node setup misses correct start/stop

[Caspar Clemens Mierau]

Binary package hint: munin

When installing munin-node on Ubuntu Jaunty with all recent updates applied, the initial plugin configuration is not read by munin as the order of start/stop is wrong. Therefore you have to restart munin-node manually once. See the following log which shows the installation, list, restart, list:

I can confirm this bug in Jaunty (munin-node 1.2.6-8ubuntu3) as well as in Karmic (munin-node 1.2.6-8ubuntu3).

[Andreas Olsson (andol)]

Actually, there is a munin-node 1.2.6-12ubuntu1 uploaded to Karmic. It just haven't reached the archives yet, due to an i386 build issue. I did a local build of munin-node 1.2.6-12ubuntu1, and it still contains this bug.

Anyway, this problem can be fixed by editing debian/munin-node.postinst and move the two "invoke-rc.d munin-node restart", located inside the init_plugins() function. I'll upload a debdiff once the current build issue is resolved.

[Launchpad Janitor (janitor)]

This bug was fixed in the package munin - 1.2.6-13ubuntu2

---------------
munin (1.2.6-13ubuntu2) karmic; urgency=low

  * Don't autoconf the plugin postgres_space_ (LP: #414232)
  * Restart munin-node after plugin initiation (LP: #406276)
