Do not clean new active version

[jackmort37]

Hi,
After upgrading and before rebooting to the newly built kernel, eclean-kernel is detecting the new installed kernel as a candidate for renewal, even if using the -n option. For example, while running kernel 4.14.8-gentoo-r1, after installing and compiling 4.14.10-gentoo-r1, this version is considered as "old" on my system, even if it's select through eselect-kernel :

gateway boot # eselect-kernel list
Available kernel symlink targets:
[1] linux-4.14.8-gentoo-r1
[2] linux-4.14.10-gentoo-r1 *
gateway boot # eclean-kernel -p
The following kernels would be removed:

== [4.14.6-gentoo] ==
Rationale:
[-] stale files (no matching kernel)
Files:

• /usr/src/linux-4.14.6-gentoo
• /lib/modules/4.14.6-gentoo

== [4.14.7-gentoo] ==
Rationale:
[-] stale files (no matching kernel)
Files:

• /usr/src/linux-4.14.7-gentoo
• /lib/modules/4.14.7-gentoo

== [4.14.10-gentoo] ==
Rationale:
[-] stale files (no matching kernel)
Files:

• /usr/src/linux-4.14.10-gentoo
• /lib/modules/4.14.10-gentoo

== genkernel-x86_64-4.14.10-gentoo-r1 ==
Rationale:
[-] old
Files:

• /boot/System.map-genkernel-x86_64-4.14.10-gentoo-r1
• /boot/initramfs-genkernel-x86_64-4.14.10-gentoo-r1
• /boot/kernel-genkernel-x86_64-4.14.10-gentoo-r1
• /usr/src/linux-4.14.10-gentoo-r1
• /lib/modules/4.14.10-gentoo-r1

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

gateway boot # uname -a
Linux gateway 4.14.8-gentoo-r1 #1 SMP Thu Dec 21 11:12:28 CET 2017 x86_64 Intel(R) Atom(TM) CPU C2550 @ 2.40GHz GenuineIntel GNU/Linux

You have to first reboot to newer kernel before using the cleaner. In older version, this was not an issue.

Would it be possible to fix this ?

Also having the same issue. Below, 4.17.6 should not be considered for deletion since that would leave me with no kernel. -n 1 doesn't have any effect here like I would expect it to, even if I am not booted into that kernel.

# uname -a
Linux limelight 4.17.3-gentoo-limelight #1 SMP Mon Jul 2 10:18:54 EDT 2018 x86_64 Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz GenuineIntel GNU/Linux
# eclean-kernel -p -n 1
The following kernels would be removed:

== [4.16.8-gentoo-limelight] ==
Rationale:
[-] stale files (no matching kernel)
Files:
! /usr/src/linux-4.16.8-gentoo (does not exist)
- /lib/modules/4.16.8-gentoo-limelight

== [4.17.4-gentoo-limelight] ==
Rationale:
[-] stale files (no matching kernel)
Files:
! /usr/src/linux-4.17.4-gentoo (does not exist)
- /lib/modules/4.17.4-gentoo-limelight

== 4.17.6-gentoo-limelight ==
Rationale:
[-] old
Files:
- /boot/vmlinuz-4.17.6-gentoo-limelight
- /usr/src/linux-4.17.6-gentoo
- /lib/modules/4.17.6-gentoo-limelight
- /boot/System.map-4.17.6-gentoo-limelight
