old stuff in /usr/lib/modules

Hi,

i just noticed that I have lots of old stuff under /usr/lib/modules/ going back to kernel 4.20.10. Is there a mechanism to clean up die directory and remove old modules with the corresponding linux image?

Re: old stuff in /usr/lib/modules

If the modules are provided by a kernel package they would be removed when that kernel package is removed.
Does pacman show the modules as being owned by any package?

pacman -Qo /usr/lib/modules/path/to/some/modeule

Re: old stuff in /usr/lib/modules

Doesn't look like pacman is taking care of this:
[frank@defiant ~]$ uname -a
Linux defiant 5.3.1-arch1-1-ARCH #1 SMP PREEMPT Sat Sep 21 11:33:49 UTC 2019 x86_64 GNU/Linux

[frank@defiant ~]$ pacman -Qo /usr/lib/modules/5.3.1-arch1-1-ARCH/modules.builtin
/usr/lib/modules/5.3.1-arch1-1-ARCH/modules.builtin is owned by linux 5.3.1.arch1-1

this shows that the modules of current running kernel are owned by the linux package. However if I run

[frank@defiant ~]$ pacman -Qo /usr/lib/modules/4.20.10-arch1-1-ARCH/modules.builtin
error: No package owns /usr/lib/modules/4.20.10-arch1-1-ARCH/modules.builtin

So looks as if they resided from updates of the linux package

Re: old stuff in /usr/lib/modules

Did you ever install one of the various "keep my kernel modules on update" hooks?

Re: old stuff in /usr/lib/modules

I have kernel-modules-hook installed
https://github.com/saber-nyan/kernel-modules-hook
but did not enable the linux-modules-cleanup.service, guess this will do the job
