I'm using this script to automate the process:

$ cat /etc/kernel/postinst.d/70-emerge-module-rebuild
#!/bin/bash
exec env -i PATH=$PATH /usr/bin/emerge -1v --usepkg=n @module-rebuild

(I don't know why "env -i PATH=$PATH" is needed but otherwise it won't
work correctly sometimes)


You could add "--changed-deps=n" there because otherwise it won't play
well with using "--changed-deps" as a default.

Now, when you run "make modules_install install", it will automatically
rebuild kernel modules.

BTW, I have another script to also install the kernel in systemd-boot
which also rebuilds initramfs (dracut here):

$ cat /etc/kernel/postinst.d/zz-systemd-boot
#!/bin/bash
/usr/bin/kernel-install remove $1 $2
/usr/bin/kernel-install add $1 $2
