Is it safe to delete /var/lib/dkms/vboxhost after unistallation of vbox?

So a while ago I switched from virtualbox to libvirt.

Now I have leftovers in my system which dracut is mentioning in every update. I want to get rid of it an after reading this topic:

and then this one:

I thought to myself “just purge the directories and be happy” - but better safe then sorry, hence the question…

my dkms status:

And I have neither vbox or zfs installed.

try to move it, maybe to home dir, then do an update. Hopefully someone will pop in with a more useful answer if that fails.

Take a look in /var/lib/dkms and see if you have some leftover stuff in there. If you find anything, check which package owns it, if no package owns it, delete it.

Well. there is some stuff in it:

ll /var/lib/dkms
total 8,0K
-rw------- 1 root root 1,7K 10. Sep 2023  mok.key
-rw-r--r-- 1 root root  811 10. Sep 2023  mok.pub

drwxr-xr-x 1 root root  114 13. Dez 2024  zfs/

And here starts the real problem:

And these are just the tips of the iceberg, I came down to this:

pacman -Qo /var/lib/dkms/vboxhost/7.0.10_OSE/6.5.2-arch1-1/x86_64/module/vboxdrv.ko.zst
error: No package owns /var/lib/dkms/vboxhost/7.0.10_OSE/6.5.2-arch1-1/x86_64/module/vboxdrv.ko.zst

Do I really have to do this by hand for every folder, subfolder, link and so on? This really is a choire…

You could use find -exec but, honestly, if you don’t have virtualbox or zfs installed anymore, there should be no harm in removing the entire directories.

Just because I am a coward:

You are speaking of

rm -rF /var/lib/dkms/zfs/ & rm -rF /var/lib/dkms/vboxhost/
