Hello again guys, how are you? I hope you're fine.

I remember someone told me a program to use to remove old kernels in 
order to get more space on /boot, i tried to search the original message 
that the guy sent me trough this list, but i cannot find it.

Here's a screenshot of my /boot folder:

I guess the kernel version i use is this one:

Could someone tell me a method to remove the old kernels in order to get 
more space in /boot?

Thank you, and regards,

Guillermo.

I found it for you.  The package is app-admin/eclean-kernel.  I think
there is a wiki page on the Gentoo website for that.  I recall it being
pretty easy to use. 

Hope that helps.

Bear in mind, if the OP is running 5.15.10, that's the second oldest 
kernel in the list. If he's got five newer kernels there, is 
eclean-kernel going to assume the live kernel is out-of-date and delete 
it? NOT a good idea.

The OP needs to make sure that both 5.15.41 and 5.15.48 are in his boot 
menu, AND that they both work, before risking clearing out the rest ...

The current kernel is never removed by eclean-kernel.

Since the grub boot menu includes all kernels in /boot by default as
far as i know, it is probably necessary to run eclean-kernel with
--destructive and re-generate the boot menu afterwards.

I've never used the tool.  I clean mine manually.  That way I know what
is going on.  Right now, I can't get a new kernel to boot cleanly.  I'm
stuck with a older one but it works.  I've tried two different version
but still fails with something.  Maybe next time.

What kernels are in your grub.cfg / boot menu. If they're not in there, 
just delete them from /boot.

It's normal to have your latest kernel in the boot menu, and one backup 
kernel.

So, for every kernel NOT in your boot list, cd into /boot and, as root, 
do "rm -i *x.y.z*" where x.y.z is the kernel version you want to get rid 
of. It'll query what files it's going to delete, but so long as it looks 
sensible, say "y" and get rid of it.

It looks like you've got seven kernels there, so five sevenths space 
freed up is quite a lot ...

Wol

Again, thank you all for your help :)

Now do a ls -al for /boot.  There has to be something in there taking up
all that space.  ;-)

Glad you feeling better.

[gentoo-user] Boot has no space left.

[Guillermo García]

Hello,

I was updating my gentoo install, and now it says that /boot has 0 
bytes, however i don't know why since i never save anything in that folder.

Any idea on what can i do?

Thanks.

I'd start by doing this:

du -shc /boot/* | sort -h

That will show the size of files in /boot and sort them from smallest to
largest. It could be that you have a large number of kernels and maybe
init thingys in there.  If so, some house cleaning may be required.

Also check the output of mount, or findmnt, to determine if /boot is the 
mountpoint of a partition and if it is currently mounted or not.

The /boot directory is typically where the boot manager files are installed, as 
well as the kernel & initrd images, kernel config and System.map files.

app-admin/eclean-kernel can help with automating the house cleaning. 😉

Hello,

Check if there are old kernels (posibly along with initramfs if you use
them). After a while (especially if your /boot partition is not that
big or you use testing kernels) thay can add up to quite some
megabytes.

Hope that helps
