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. -----BEGIN PGP SIGNATURE-----

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

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 ...

Cheers,
Wol

Thank you, and regards,

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.

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eclean-kernel going to assume the live kernel is out-of-date and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.

The kernel choice algorithm is quite simple:

1. If the kernel is currently used, don't remove it;
2. If the kernel is referenced by a bootloader, don't remove it
(unless ``--destructive``);
3. If auxiliary files do not map to existing kernel, remove them;
4. If ``--all`` is used, remove the kernel;
5. If kernel is not within *N* newest kernels (where *N* is the
argument to ``-n``), remove it.

<https://github.com/mgorny/eclean-kernel/blob/master/README.rst>

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.

Kind regards, tastytea

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.
