Too many initramfs files are removed

[JulienDlq]

I have the following inside my /boot.

ls -1 /boot
amd-uc.img
EFI
grub
initramfs-5.8.1-gentoo-x86_64.img
initramfs-5.8.1-gentoo-x86_64.old.img
initramfs-5.8.2-gentoo-x86_64.img
intel-uc.img
lost+found
System.map-5.8.1-gentoo-x86_64
System.map-5.8.1-gentoo-x86_64.old
System.map-5.8.2-gentoo-x86_64
vmlinuz-5.8.1-gentoo-x86_64
vmlinuz-5.8.1-gentoo-x86_64.old
vmlinuz-5.8.2-gentoo-x86_64

If I perform the following command I can see that only the .old kernel and related files will be removed.

eclean-kernel -d -n 2 -p            
These are the kernels which would be removed:
- 5.8.1-gentoo-x86_64.old: unwanted
kernel-install will be called to perform prerm tasks.

In order to be sure, I run the following command.

eclean-kernel -l

If I run the following command, it seems to perform what it is expected.

eclean-kernel -d -n 2

- /boot/initramfs-5.8.1-gentoo-x86_64.old.img
Removed 1 kernels

But if I double check, actually, eclean-kernel also removed the /boot/initramfs-5.8.1-gentoo-x86_64.img file. I didn't asked for that!

ls -1 /boot

It seems that initramfs management is buggy. :cry:

I also tried with 2.99.1. I have the same issue.

Ok even if I tell my scripts to save previous initramfs with .img.old extension instead of .old.img, I still have the same issue.

But it seems that grub-mkconfig do not recognise the right initramfs for the right kernel!

grub-mkconfig -o /boot/grub/grub.cfg

If a rename back the old initramfs file to /boot/initramfs-5.8.1-gentoo-x86_64.old.img.

Everything is fine.

So the old initramfs file must be named initramfs-<version>.old.img.

Do I understand correctly that it's removing a file even though it doesn't say it's removing it?

Could you verify that it isn't kernel-install removing it? E.g. rename it or move out of PATH, and try eclean-kernel then.

[runcom]

I'm having the very same issue here

[runcom]

Could you verify that it isn't kernel-install removing it? E.g. rename it or move out of PATH, and try eclean-kernel then.

I can confirm it's kernel-install removing the other files indeed :man_facepalming: I'll run with --no-kernel-install and check it works

[runcom]

I can confirm that running with --no-kernel-install "solves" the issue as in, it doesn't delete the initiramfs for the currentl (not old) kernel. Running without does indeed call kernel-install and as a result, it removes the initramfs (the "old" one). Any way to report this upstream in systemd perhaps?

[mgorny]

Do you have dracut installed? I think this removal may be happening due to /usr/lib/kernel/install.d/50-dracut.install. I think an easy way to confirm would be to remove that file and see if it still happens.

In any case, this is going to be hard because there are so many different /boot layouts…

[xfzv]

Same here, my initramfs images are deleted despite not being listed as being removed by eclean-kernel.

I'm using dracut. Removing /usr/lib/kernel/install.d/50-dracut.install doesn't make any difference for me.

However, using --no-kernel-install as suggested by @runcom also solves the issue on my end.

Edit: also tried --exclude initramfs but the initramfs images were still deleted. Only --no-kernel-install seems to do the trick.
