[Pkg-nagios-devel] Bug#361239: nagios2 cannot start, if /var is on a tempfs

[Herbert Straub]

Package: nagios2
Version: 2.0-1

The process nagios2 cannot be started, if the /var directory is on a  
tempfs, because the directory /var/run/nagios2 doesn't exists. This  
directory will be created in the nagios2-common.postinst script. After  
a reboot, the directory doesn't exists anymore. A second aspect is the  
hardcoded path in the postinst script:

install -d -onagios -gnagios -m750 /var/run/nagios2

and the startup script will create the path dynamically from the  
lock_file statement in the Nagios configuration file:
THEPIDFILE="$(grep lock_file $NAGIOSCFG | awk '{print $2}' FS="=")"
After a change of the lock_file statement, the nagios process cannot  
start anymor.

This patch will correct this phenomenon:
diff -u nagios2.ORIG  nagios2
