on a system running bookworm and the latest amd64 kernel /usr/lib/nagios/plugins/check_running_kernel warns me that the running kernel doesnt match the on-disk kernel, while it *is* running the latest kernel. (line breaks added for better readability.)
In the moment I'm trying to understand how the script works. My current state is: it checks, which compression mode is used, for the kernel images in /boot/ (which seems to be xz for bookworm), then it decompresses the xz compressed part of the kernel images and searches for "Linux version". The part after "Linux version" is compared to the content of /proc/version. Unfortunately there is a difference: /boot/vmlinuz: Linux version 6.1.0-5-amd64 (debian-ker...@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) # SMP PREEMPT_DYNAMIC Debian 6.1.12-1 (2023-02-15) /proc/version Linux version 6.1.0-5-amd64 (debian-ker...@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.12-1 (2023-02-15) So it could be a bug in the kernel configuration too. All this worked fine on Debian stable. I did not check if there was another compression method in use. I could not dig further, I failed to extract the xz compressed part of the kernel correctly. Not sure if this is useful. Hilmar -- sigfault
