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

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?

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

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

Take in account marked for removal kernels.

The calculation how many kernels to remove before this commit was not
taking in account kernels which are already marked for removal. Thus
when adding new kernels for removal the logic would end up removing more
than the user requested.

This commit just adds the already marked for removal kernels to the
calculation.

Should fix projg2#15.

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.
