[Pkg-nagios-devel] Bug#1117606: nagios-nrpe-server.service: Referenced but unset environment variable evaluates to an empty string: NRPE_OPTS

[Larsen]

Package: nagios-nrpe-server
Version: 4.1.3-1


Dear maintainer,

having upgraded systems to Debian Trixie, I noticed this warning in 
/var/log/daemon.log:
Oct  8 15:48:17 vm-lm-deb64 (nrpe)[20832]: nagios-nrpe-server.service: 
Referenced but unset environment variable evaluates to an empty string: 
NRPE_OPTS

Probably a new feature of systemd (257.8-1~deb13u2).

The reason for this is that NRPE_OPTS is used in 
"/etc/systemd/system/multi-user.target.wants/nagios-nrpe-server.service" 
but is commented out in "/etc/default/nagios-nrpe-server".

~# grep ExecStart 
/etc/systemd/system/multi-user.target.wants/nagios-nrpe-server.service
ExecStart=/usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -f $NRPE_OPTS

~# grep NRPE_OPTS /etc/default/nagios-nrpe-server
# NRPE_OPTS are any extra cmdline parameters you'd like to pass along to 
the
#NRPE_OPTS="-n"
