 Posted: Thu Mar 28, 2024 9:25 pm Post subject: modules question (can I remove) |
 |
|
This is my new uname with profile 46:
Linux yoda 6.6.21-gentoo #1 SMP PREEMPT_DYNAMIC Tue Mar 12 09:48:17 PDT 2024 x86_64 Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz GenuineIntel GNU/Linux
I am assuming I can remove modules on kernels I don't have installed.
I also assume I would remove these manually.
? Aside from removing modules. What are other clean up procedures after updating a kernel?
Please throw me a bone.

Typically it is recommended to keep one backup kernel in /boot along with its modules in /lib/modules and sources in /usr/src which in case you need to revert to old kernel you change symlink in /usr/src/linux to the kernel you are using. Of course there should be entry in GRUB or whatever boot loader you are using. Said kernel you should be sure works fine.
All the rest can be removed from /boot, /usr/src and /lib/modules. In boot you might also have initramfs files if you use those for booting.
Kernels emerged by portage should be also unemerged - though I don't think it matters if you do it before or after deleting files.
There might also be copies of kernel configs in /etc/kernels if you use genkernel to build kernel. Those don't take that much disk space though. And lastly any entries for old kernels from your boot configuration.
Other than that... not 100% sure but it would seem that is it.
