[Pkg-nagios-devel] Bug#883088: nagios-plugins-contrib: check_running_kernel error on Marvell kernels

[John Lines]

Package: nagios-plugins-contrib
Version: 21.20170222
Severity: normal
Tags: patch

Dear Maintainer,

The /boot directory on /boot includes /vmlinuz.old - a link to the previously installed kernel.
This is detected by check_running_kernel, which incorrectly detects it as the current installed
kernel.

Excluding it from the candidates for the on disk kernel fixes the issue.

John
