 |

All the guides online seem to be concerned with removing old kernels, I'm looking for
help removing all kernels that aren't the one I'm using now (which is the old one), or new kernels.  |

Why don't you just copy the working config in the kernel you are in to the new kernel and run make syncconfig?
https://wiki.gentoo.org/wiki/Kernel/Upgrade
Here's my (now fixed with --oneshot) kernel upgrading system (as root):
YMMV
| Code: |
cp /usr/src/linux/.config ~/kernel-config-`uname -r`
eselect kernel list
eselect kernel set 2
mount /boot
cd /usr/src/linux
zcat /proc/config.gz > /usr/src/linux/.config
make syncconfig
make && make modules_install
make install
grub-mkconfig -o /boot/grub/grub.cfg
emerge --oneshot nvidia-drivers
emerge --oneshot vmware-modules
umount /boot
reboot

Muso instead of
| Code: | emerge --oneshot nvidia-drivers
emerge --oneshot vmware-modules |
why you don't run emerge @module-rebuild? This command rebuild all modules installed through portage in your system.

Have you checked the eclean-kernel tool? https://wiki.gentoo.org/wiki/Kernel/Removal#Removing_kernel_leftovers
It removes the kernels that are no longer refereced, so theoretically you should be able to hold your current old kernel and remove the older or newer ones in case they're no longer referenced. |

OoooOoOoooOo, Thank you everyooooone.
I actually had more than one botched kernels installed, lets just say I made many attempts. 
But now I can clean up all the others and do a rebuild. |

Will check on the next kernel. I wasn't sure if it would pull in the vmware-modules.
| Code: | emerge -p @module-rebuild
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] x11-drivers/nvidia-drivers-415.18
[ebuild R ] net-wireless/rtl8812au_aircrack-ng-5.2.20_p20180904-r1
[ebuild R ] app-emulation/vmware-modules-330.0.2
|
Nice! Process updated.

Theoretically yes because is linux-mod eclass that add module to list (and vmware-module inherit from linux-mod), you can check reading file /var/lib/module-rebuild/moduledb

One thing that is nice when you want to experiment with the kernel is to give it a "local Version". If you give it a local version of something like -test it will append -test to the kernel,config, and modules directory so it won't overwrite/clobber your working kernel of the same version when you make install.
| Code: | | General Setup - > () Local version - append to kernel release |

skellr,
There is a downside to local version too. Its not, or at least, wasn't in the past, respected by all out of tree kernel modules.
nvidia-drivers was one popular case.
Thu fix for that is to edit the kernel Makefile which starts
| Code: | # SPDX-License-Identifier: GPL-2.0
VERSION = 4
PATCHLEVEL = 19
SUBLEVEL = 0
EXTRAVERSION = -gentoo |
and change the EXTRAVERSION. Then run in the kernel tree.
