As I was trying to find out what would work and if I was doing something wrong getting rid of old kernels.... After upgrading a new kernel for a week I will do apt autoremove to get rid of the old kernel(s). Debian will automatically keep the current kernel and the previous in the /boot folder. Somehow, I get the feeling there either is a bug which causes the /usr/lib/modules/ folder not to be cleaned up or there are somehow links to it from packages that were updated when a specific kernel was active. Just created a snapshot of my servers and then did: apt autoremove apt purge apt clean and I still have a working system so it will not just get rid of all installed packages. :-) But... I still also have all those folders in /usr/lib/modules I am now cleaning some by hand. Running kernel -22 and having -21 as backup kernel I did: xxxxx:/usr/lib/modules# rm -rd 5.10.0-16-amd64/ xxxxx:/usr/lib/modules# rm -rd 5.10.0-17-amd64/ xxxxx:/usr/lib/modules# rm -rd 5.10.0-18-amd64/ etc. and then a reboot to see if all is well. ;-) No "error" in syslog and my dhcp server is still running. :-) But.... is this a bug in the cleanup of an old kernel or are there realy links to the old modules, links that are now broken? If it s a bug, who will report it? I know only enough to report the symptoms. BTW I noticed this not only in my bullseye systems but also in my older busters systems, The folders are just smaller and therefore it did not realy impact my diskspace on / which is why I never noticed it.
