I don't recall it doing that way either. I've had a kernel go bad before and had to reboot a old kernel. If it deleted the files in the old modules directory, then my GUI wouldn't come up because the video drivers would no longer be there. I think I'd remember that. :/ Just for giggles, I did a ls for my current installed kernel versions modules directory. This is what it shows. root@fireball / # ls -al /lib/modules/4.19.40-gentoo/ total 80 drwxr-xr-x 4 root root 4096 May 3 2020 . drwxr-xr-x 14 root root 4096 Jul 1 01:39 .. lrwxrwxrwx 1 root root 29 May 15 2019 build -> /usr/src/linux-4.19.40-gentoo drwxr-xr-x 3 root root 4096 Apr 23 2020 kernel -rw-r--r-- 1 root root 334 May 3 2020 modules.alias -rw-r--r-- 1 root root 530 May 3 2020 modules.alias.bin -rw-r--r-- 1 root root 12021 Apr 23 2020 modules.builtin -rw-r--r-- 1 root root 15879 May 3 2020 modules.builtin.bin -rw-r--r-- 1 root root 156 May 3 2020 modules.dep -rw-r--r-- 1 root root 321 May 3 2020 modules.dep.bin -rw-r--r-- 1 root root 0 May 3 2020 modules.devname -rw-r--r-- 1 root root 36 Apr 23 2020 modules.order -rw-r--r-- 1 root root 55 May 3 2020 modules.softdep -rw-r--r-- 1 root root 3838 May 3 2020 modules.symbols -rw-r--r-- 1 root root 4271 May 3 2020 modules.symbols.bin lrwxrwxrwx 1 root root 29 Apr 23 2020 source -> /usr/src/linux-4.19.40-gentoo drwxr-xr-x 2 root root 4096 Feb 15 01:23 video root@fireball / # ls -al /lib/modules/5.6.7-gentoo/ total 184 drwxr-xr-x 4 root root 4096 Apr 20 01:47 . drwxr-xr-x 14 root root 4096 Jul 1 01:39 .. lrwxrwxrwx 1 root root 27 May 2 2020 build -> /usr/src/linux-5.6.7-gentoo drwxr-xr-x 3 root root 4096 May 9 2020 kernel -rw-r--r-- 1 root root 334 Apr 20 01:47 modules.alias -rw-r--r-- 1 root root 530 Apr 20 01:47 modules.alias.bin -rw-r--r-- 1 root root 12558 May 9 2020 modules.builtin -rw-r--r-- 1 root root 0 Apr 20 01:47 modules.builtin.alias.bin -rw-r--r-- 1 root root 16054 Apr 20 01:47 modules.builtin.bin -rw-r--r-- 1 root root 101792 May 9 2020 modules.builtin.modinfo -rw-r--r-- 1 root root 193 Apr 20 01:47 modules.dep -rw-r--r-- 1 root root 401 Apr 20 01:47 modules.dep.bin -rw-r--r-- 1 root root 0 Apr 20 01:47 modules.devname -rw-r--r-- 1 root root 36 May 9 2020 modules.order -rw-r--r-- 1 root root 55 Apr 20 01:47 modules.softdep -rw-r--r-- 1 root root 3768 Apr 20 01:47 modules.symbols -rw-r--r-- 1 root root 4321 Apr 20 01:47 modules.symbols.bin lrwxrwxrwx 1 root root 27 May 9 2020 source -> /usr/src/linux-5.6.7-gentoo drwxr-xr-x 2 root root 4096 Apr 20 01:47 video root@fireball / # ls -al /lib/modules/5.10.46-gentoo/ total 184 drwxr-xr-x 3 root root 4096 Jul 1 01:39 . drwxr-xr-x 14 root root 4096 Jul 1 01:39 .. lrwxrwxrwx 1 root root 29 Jul 1 01:39 build -> /usr/src/linux-5.10.46-gentoo drwxr-xr-x 3 root root 4096 Jul 1 01:39 kernel -rw-r--r-- 1 root root 108 Jul 1 01:39 modules.alias -rw-r--r-- 1 root root 335 Jul 1 01:39 modules.alias.bin -rw-r--r-- 1 root root 12739 Jul 1 01:39 modules.builtin -rw-r--r-- 1 root root 0 Jul 1 01:39 modules.builtin.alias.bin -rw-r--r-- 1 root root 16480 Jul 1 01:39 modules.builtin.bin -rw-r--r-- 1 root root 103263 Jul 1 01:39 modules.builtin.modinfo -rw-r--r-- 1 root root 37 Jul 1 01:39 modules.dep -rw-r--r-- 1 root root 74 Jul 1 01:39 modules.dep.bin -rw-r--r-- 1 root root 0 Jul 1 01:39 modules.devname -rw-r--r-- 1 root root 36 Jul 1 01:39 modules.order -rw-r--r-- 1 root root 55 Jul 1 01:39 modules.softdep -rw-r--r-- 1 root root 49 Jul 1 01:39 modules.symbols -rw-r--r-- 1 root root 12 Jul 1 01:39 modules.symbols.bin lrwxrwxrwx 1 root root 29 Jul 1 01:39 source -> /usr/src/linux-5.10.46-gentoo root@fireball / # I currently have three available kernels, one I did recently and have yet to reboot and use.

It should install to the new location as if it is a new install, since it is a new kernel, it sort of is a new install since it has never been installed for THAT kernel before. Has this changed? Is it a setting somewhere that is a new default? Can't imagine what that is tho. I know I don't like the change if it has because I tend to keep multiple kernels installed as fall backs. If I have to fall back on a older kernel, I expect everything to work like it did the last time I used that kernel as far as drivers go, including and especially video drivers. So, let me test this theory a bit. I used eselect to point to new kernel. I emerged the nvidia drivers again and here is the listing now, old kernels and the one I've yet to use but just re-emerged the drivers for. root@fireball / # ls -al /lib/modules/4.19.40-gentoo/video/ total 28020 drwxr-xr-x 2 root root 4096 Feb 15 01:23 . drwxr-xr-x 4 root root 4096 May 3 2020 .. -rw-r--r-- 1 root root 80504 May 3 2020 nvidia-drm.ko -rw-r--r-- 1 root root 27162104 May 3 2020 nvidia.ko -rw-r--r-- 1 root root 1437216 May 3 2020 nvidia-modeset.ko root@fireball / # ls -al /lib/modules/5.6.7-gentoo/video/ total 43536 drwxr-xr-x 2 root root 4096 Apr 20 01:47 . drwxr-xr-x 4 root root 4096 Apr 20 01:47 .. -rw-r--r-- 1 root root 92224 Apr 19 22:38 nvidia-drm.ko -rw-r--r-- 1 root root 40951920 Apr 19 22:38 nvidia.ko -rw-r--r-- 1 root root 1566736 Apr 19 22:38 nvidia-modeset.ko -rw-r--r-- 1 root root 1950824 Apr 19 22:38 nvidia-uvm.ko root@fireball / # ls -al /lib/modules/5.10.46-gentoo/video/ total 43532 drwxr-xr-x 2 root root 4096 Jul 7 19:24 . drwxr-xr-x 4 root root 4096 Jul 7 19:24 .. -rw-r--r-- 1 root root 93000 Jul 7 19:22 nvidia-drm.ko -rw-r--r-- 1 root root 40953232 Jul 7 19:22 nvidia.ko -rw-r--r-- 1 root root 1566784 Jul 7 19:22 nvidia-modeset.ko -rw-r--r-- 1 root root 1947848 Jul 7 19:22 nvidia-uvm.ko root@fireball / # So, old version of modules are still there as they should be and new modules installed for the new kernel version.

Maybe a USE flag above will change that?? I dunno. Dale :-) :-)
