eclean-kernel's Issues

No module named 'zstandard'

Hi. This appears on latest app-admin/eclean-kernel-2.99.3.
Please see logs:

# eclean-kernel -d -n2
eclean-kernel has met the following issue:

  MissingDecompressorError('Kernel file /boot/initramfs-5.10.57-gentoo-dist.img is compressed with zstandard, but the required decompressor is not installed')

If you believe that the mentioned issue is a bug, please report it
to https://github.com/mgorny/eclean-kernel/issues. If possible,
please attach the output of 'eclean-kernel --list-kernels' and your
regular eclean-kernel call with additional '--debug' argument.

eclean-kernel --list-kernels - same output.

/boot no longer automatically mounted

Version: 2.99.2

When /boot isn't mounted, I get this error message:

eclean-kernel has met the following issue:

SystemError('No vmlinuz found. This seems ridiculous, aborting.')

When /boot is mounted, it works. It automatically mounted with 0.4.3. eclean-kernel --help lists the --no-mount option, which indicates that it should automatically mount by default.

Debug output:

Unable to load any modules after running eclean-kernel

Hello.
I've found rather critical bug that caused my server malfunction for several hours (time needed to recompile a kernel).

Steps to reproduce:

Compile a kernel with genkernel.
Recompile the same kernel version with genkernel again (for example, I decided to recompile the kernel with different config).
Run eclean-kernel -n 1

After the second compilation you have the following layout:

lily ~ # eclean-kernel -l

For some reason, eclean-kernel removed most of the /lib/modules/5.17.9-gentoo-x86_64/modules.* files, leaving only modules.builtin, modules.builtin.modinfo and modules.order.

This makes the system unable to load any modules. I've accidentally found this after a reboot - hardware attached to my server wasn't working because the modules were not loaded.

NotADirectoryError(20, 'Not a directory')

Haven't seen this before? Is the issue on my end?

eclean-kernel has met the following issue:

If you believe that the mentioned issue is a bug, please report it

Can’t handle different file names.

I stopped calling my kernel files “vmlinuz” a long time ago, because it doesn’t fit modern systems and formats.
And eclean-kernel just removed ALL my kernels! If the config files hadn’t been saved somewhere else too, they’d be gone and I would have had to re-install from backups before rebooting, or been left with a broken system. :/

My layout is as follows: In /boot, there are symlinks
.config -> /boot/.config-$currentVersion
.config.stable -> /boot/.config-$lastVersion
System.map -> /boot/System.map-$currentVersion
System.map.stable -> /boot/System.map-$lastVersion
kernel -> /boot/kernel-$currentVersion
kernel.stable -> /boot/kernel-$lastVersion

E.g.
currentVersion=5.13.10-zen1.0
lastVersion=5.13.4-zen1.0

eclean-kernel deleted every System.map-* and every kernel-* and then all /etc/src/linux-* directories too, including the .config files therein.

Looking at its, frankly, gigantic amount of source code for such a simple program, I cannot even locate where to alter what it looks for to determine which kernels are still in use. It seems to all be much too generic code. So I’m even more surprised it failed for my case. (Did it fail because of the symlinks?)

So can you please enable people to specify how they named their stuff inside /boot?
Because like this, eclean-kernel is not only useless for all but “I don’t care, just do it the standard way” cases… when the whole point of Gentoo is that you care and customize… but it also can be out-performed by a 5-line bash script. (Or a Haskell one-liner, albeit in write-only code ;)

As png files have same names as accompanying kernel images, their removal should be done only when vmlinux file is deleted.

Proposal: Preserve N most recent minor versions

I'm willing to take a shot at a patch for this, but wanted to see if someone else had already been working on this.

eclean-kernel -n 3 makes a list of the 3 most recent versions to preserve.
eclean-kernel -N 3 could make a list of kernel versions X.Y.Z where X and Y are fixed and Z is maximized.
eclean-kernel -n3 -N3 could make both lists and preserve any kernel which is a member of either set.

For example, say you have the following kernels on disk: 5.11.16, 5.11.15, 5.11.14, 5.11.13, 5.11.12, 5.10.16, 5.10.15, 5.10.10, 5.9.14, 5.9.12, 4.20.5 (a subset of my actual current situation)

-n3 would remove all but 5.11.16, 5.11.15, 5.11.14
-N3 would remove all but 5.11.16, 5.10.16, 5.9.14
-n3 -N3 would remove all but 5.11.16, 5.11.15, 5.11.14, 5.10.16, 5.9.14

Thoughts?

eclean-kernel has met the following issue: MissingDecompressorError('Kernel file /boot/initramfs-5.13.12-gentoo-x86_64.img is compressed with lzo, but the required decompressor is not installed')

However, emerge --info emerge app-arch/lzop shows:

...
=================================================================
                        Package Settings

app-arch/lzop-1.04::gentoo was built with the following:

the blspec layout doesn't consider /etc/kernel/entry-token

I recently installed gentoo and it comes with /etc/kernel/entry-token set to gentoo. In this case, machine-id is replaced by gentoo and kernels end up in directories like /boot/gentoo/6.1.8-gentoo-dist/{linux, initrd}

Prompt should indicate default option

Note this is tested with v0.4.3 but I didn't spot any significant changes in current master so I assume this is still happening in current master:

Run eclean-kernel --ask --destructive --all.
You will get prompted like

Remove 5.11.15-gentoo-x86_64 (unwanted)? [Yes/No]
When you now press Enter, output will be
- Removing kernel 5.11.15-gentoo-x86_64 (unwanted)
- /boot/vmlinuz-5.11.15-gentoo-x86_64
- /boot/System.map-5.11.15-gentoo-x86_64
- /boot/initramfs-5.11.15-gentoo-x86_64.img
- /lib/modules/5.11.15-gentoo-x86_64
- /usr/src/linux-5.11.15-gentoo

This could be unexpected. How about indicating default action like known from make oldconfig? I.e. instead of

[Yes/No]

show

[YES/no]

so it should be clear that pressing Enter without any further input will proceed with removal.

Too many initramfs files are removed

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

System.map-5.8.1-gentoo-x86_64.old

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

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. 😢

Repository description is outdated

Repository description says „Old version of kernel cleanup tool (unmaintained, bugs will be fixed only if patch is provided)”, which doesn't seem to be the case now.

Current implementation of bootloader processing does not work well with symlinks

This is a followup of #41 .

Briefly, with the following LILO configuration (all bootloaders are affected, but I only have LILO installed):

image=/boot/vmlinuz
        label=default
        read-write
        root=/dev/sda1
        append="net.ifnames=0 init=/sbin/openrc-init sysrq_always_enabled=1"
image=/boot/vmlinuz.old
        label=old
        read-write
        root=/dev/sda1
        append="net.ifnames=0 init=/sbin/openrc-init sysrq_always_enabled=1"

and these files in /boot:

-rw-r--r-- 1 root root     512 Jan  3  2022 boot.0800
lrwxrwxrwx 1 root root      18 Aug 13 11:49 config -> config-6.4.10-test
-rw-r--r-- 1 root root  109325 Aug 13 11:49 config-6.4.10-test
-rw-r--r-- 1 root root  109229 Aug  4 08:24 config-6.4.8-test
-rw-r--r-- 1 root root  109324 Aug 10 16:45 config-6.4.9-test
lrwxrwxrwx 1 root root      17 Aug 10 16:45 config.old -> config-6.4.9-test
-rw-r--r-- 1 root root       0 Jan  2  2022 .keep
-rw------- 1 root root   23040 Aug 13 11:49 map

-rw-r--r-- 1 root root 4288104 Aug 13 11:49 System.map-6.4.10-test
-rw-r--r-- 1 root root 4286603 Aug  4 08:24 System.map-6.4.8-test
-rw-r--r-- 1 root root 4287870 Aug 10 16:45 System.map-6.4.9-test
lrwxrwxrwx 1 root root      21 Aug 10 16:45 System.map.old -> System.map-6.4.9-test
lrwxrwxrwx 1 root root      19 Aug 13 11:49 vmlinuz -> vmlinuz-6.4.10-test
-rw-r--r-- 1 root root 7913168 Aug 13 11:49 vmlinuz-6.4.10-test
-rw-r--r-- 1 root root 7909136 Aug  4 08:24 vmlinuz-6.4.8-test
-rw-r--r-- 1 root root 7911952 Aug 10 16:45 vmlinuz-6.4.9-test
lrwxrwxrwx 1 root root      18 Aug 10 16:45 vmlinuz.old -> vmlinuz-6.4.9-test

then running eclean-kernel -a, the expectation is that only the following files would be deleted (everything else is used by the bootloader):

-rw-r--r-- 1 root root  109229 Aug  4 08:24 config-6.4.8-test
-rw-r--r-- 1 root root 4286603 Aug  4 08:24 System.map-6.4.8-test
-rw-r--r-- 1 root root 7909136 Aug  4 08:24 vmlinuz-6.4.8-test

Instead, the regex substitution here fails and only the currently running kernel is preserved, which means at least one more kernel is deleted.

Do not remove kernels with versions greater than the currently running kernel

Now algorithm preserving currently running kernel. But if a new kernel is installed, but the system has not yet been booted into it, then it will be removed after running this script.

No source removal if no modules

Hi,
If I understand the source code correctly, the kernel source directory (/usr/src/linux-xxx) is tied to the module directory (/lib/modules/xxx) because it is read from a link (named build).
On one of my server, I have a kernel where CONFIG_MODULES is disabled. In this case, there is no modules directory and so, eclean-kernel is never removing my old sources.
Is there currently a way to say to eclean-kernel to remove the source directories without looking for the modules? Or could that be an option?
Thank you.

importantly: these kernels have been produced with systemd's ukify, not with dracut.

No vmlinuz found. This seems ridiculous. Perhaps `eclean-kernel` only looks in /boot?

# eclean-kernel -p
eclean-kernel has met the following issue:

  SystemError('No vmlinuz found. This seems ridiculous, aborting.')

I believe this is due to the fact that my kernels, initramfs's and friends are in /, not /boot. Can anybody confirm?

Can’t handle diferent file names.

I stopped calling my kernel files “vmlinuz” a long time ago, and eclean-kernel just removed ALL my kernels! If the config files hadn’t been saved somewhere else too, they’d be gone and I would have had to re-install from backups before rebooting, or been left with a broken system. :/

My layout is as follows: In /boot, there are symlinks
.config -> /boot/.config-$currentVersion
.config.stable -> /boot/.config-$lastVersion
. -> /boot/-$currentVersion
..stable -> /boot/-$lastVersion

Question: why, for grub2, grub.cfg is tested for "automatically generated" header?

Sorry if my question is silly, but I'm a a bit puzzled. I'm using genkernel to create and install my kernels. I tried to use eclean-kernel to remove old kernels and I noticed that it does not find any kernel referenced in grub.cfg (believe me, they are :) ).
It seems that is due to the line 30 of grub2.py, where the file is tested for the header "...DO NOT EDIT THIS FILE...". Is this the intended behavior? I'm not sure why this is done, as basically this could lead eclean-kernel to remove all kernel files even without -d parameter, that does not seems to be really safe.

eclean-kernel -n 1 -p
No outdated kernels found.
