[Pkg-nagios-devel] Bug#1128004: AW: Bug#1128004: nagios-nrpe-server: Check disk reports permission problem after reboot.

[a.sachs at vsd.volley.de]

The command is 

command[check_disks]=/usr/lib/nagios/plugins/check_disk -w 20% -c 07%

But the interesting thing is:
sudo -u nagios /usr/lib/nagios/plugins/check_disk -w 20% -c 07% 
does not have the problem.

If nrpe is started during boot, I have the problem.


After systemctl restart nagios-nrpe-server.service the problem is gone.


After 
systemctl stop getty at tty1.service
systemctl stop nagios-nrpe-server.service
systemctl start nagios-nrpe-server.service
systemctl start getty at tty1.service

the problem is back again

This issue doesn't occur on any of the trixie systems I run NRPE on.

To reproduce the issue we'll need the exact command definition.

Use `systemctl edit nagios-nrpe-server` to create a service override.

Or update the command definition to ignore /run/credentials or all tmpfs filesystems.

Kind Regards,
