@rain When it comes to my custom version of Linux-libre, I first run `make menuconfig` to apply the defaults (although I guess `make localmodconfig` will be useful in including all of the autoloaded modules and saving most of the work) and then I hand configure all relevant option in menuconfig and also disable many legacy things only useful for executing very old proprietary software.

When it's looking pretty good, I run; `make -j$(nproc) && make modules_install && make install && dracut --kver <new version> (for LUKS encrypted storage - I'd prefer it if I could go without an initramfs of course) && grub-mkconfig -o /boot/grub/grub.cfg` and I see if it boots, otherwise I continue shotgun surgery.
