eclean-kernel -n 3 removed all kernels but current one

[uzytkownik]

Today eclean-kernel -n 3 removed 4.15.0 I just compiled leaving only current one (4.14.14). Rationale given was old.

== 4.15.0-gentoo ==

Hi, I encountered the same bug.

I was not sure I even understood the output of this command. So I tried:

# diff <(eclean-kernel -n 4 -p 2>&1) <(eclean-kernel -n 3 -p 2>&1)

Same here: Before:

$ eclean-kernel -l
genkernel-x86_64-4.15.10-gentoo:
- aux: /boot/System.map-genkernel-x86_64-4.15.10-gentoo
- kernel: /boot/kernel-genkernel-x86_64-4.15.10-gentoo
- build: /usr/src/linux-4.15.10-gentoo
- modules: /lib/modules/4.15.10-gentoo

Then after building and installing a new version and placing it in boot and grub:

$ eclean-kernel -p
The following kernels would be removed:

== genkernel-x86_64-4.15.12-gentoo ==
Rationale:
[-] old
Files:
- /boot/System.map-genkernel-x86_64-4.15.12-gentoo
- /boot/kernel-genkernel-x86_64-4.15.12-gentoo
- /usr/src/linux-4.15.12-gentoo
- /lib/modules/4.15.12-gentoo
- /boot/initramfs-genkernel-x86_64-4.15.12-gentoo

The following command would be run: grub-mkconfig -o /boot/grub/grub.cfg

--sort-order does not seem to change behavior as well

Could you give eclean-kernel -l for after state?

[mgomersbach]

$ eclean-kernel -l
genkernel-x86_64-4.15.10-gentoo:
- aux: /boot/System.map-genkernel-x86_64-4.15.10-gentoo
- kernel: /boot/kernel-genkernel-x86_64-4.15.10-gentoo
- build: /usr/src/linux-4.15.10-gentoo
- modules: /lib/modules/4.15.10-gentoo

[mgomersbach]

Or did you mean "after installing" because this is "after (e)cleaning"?

[mgorny]

Yes, I meant 'after installing' but 'before cleaning'.

[mgomersbach]

$ eclean-kernel -l

Hi,

eclean-kernel still does not recognize how many kernels to leave. The currently running kernel is 4.20.3. I updated the kernel to 4.20.4, but didn't reboot the system.

eclean-kernel only wants to leave kernel 4.20.3 and wants to delete all other ones, although I set -n to 3. In my opinion it should leave the kernels 4.20.2 to 4.20.4.

# eclean-kernel -p -n3 

...

eclean-kernel always wants to delete those kernels, it does not matter which number I set.
