Description of problem:
Nagios will not start after update/upgrade and reboot.
It is a bug in its post-install script.

Version-Release number of selected component (if applicable):
2.3-3.fc5 but also some older packages.

How reproducible:
always

Steps to Reproduce:
1. Configure nagios to start automatically after reboot:
     chkconfig --add nagios
     chkconfig nagios on
2. Upgrade to latest version from fedora extras using yum.
2. Try to look setting:
     chkconfig --list nagios

  
Actual results:
service nagios supports chkconfig, but is not referenced in any runlevel (run
'chkconfig --add nagios')

Expected results:
nagios          0:off   1:off   2:on    3:on    4:on    5:on    6:off


Additional info:
This bug is present in spec file and its preun section. You can't delete
chkconfig entry on update, only on package removation. There are these lines now:
%preun
/sbin/service nagios stop > /dev/null 2>&1 || :
/sbin/chkconfig --del %{name} || :

You must check, if it is removation or upgrade. You can use this code:
%preun
/sbin/service nagios stop > /dev/null 2>&1 || :
if [ "$1" = 0 ]; then
  /sbin/chkconfig --del %{name} || :
fi

and do not delete chkconfig entry on upgrade!

Can somebody check all fedora extras packages for this bug?
