how to safely remove kernel and extensions after switch

Postby Multimandala » Mon Jul 28, 2014 15:26

Hello, I've switched kernels with the kernel switcher from 3.14 to 3.15, it went well. [ I'm used to ubuntu terminal by the way and following tutorials ;-) ] my ' problem ' right now is that I have a whole bunch of dependent packages that are present for both kernels, exemple all the virtualbox ones, present for both 3.14 and 3.15. I looked around to find info on how to safely remove old kernels, or mask them, but I did not find easy answers. When I'll upgrade to 3.16 I'd like not to have 3 versions of all these packages around. I went to the rigo manager and I could have deleted the 3.14 sabayon kernel but I chickened out looking at the other stuff that would be removed and I don't feel like breaking my system -- right now I can live with multiple versions of packages but it is not the ideal.

So, any simple equo tutorial to follow to safely remove the older kernels without breaking anything ?

Once I'm satisfied that a new kernel is working well for me, I simply remove the old kernel, which cleans up anything that depends specifically on that kernel.

I do tend to keep one other kernel just to be safe though.

equo cares for everything ;)

Code: Select all
# equo rm -a linux-sabayon:3.14

Similar as Stupot, I usually keep 2 kernels. Latest stable and one LTS kernel. 3.14 is the most actual kernel with long term support, see
