Looks like not too many people are booting kernels like me, so
I'm going to add my crude setup to the pile :)
I compile most stuff into the kernel (at least enough so I don't
need to use an initrd/initramfs to mount / or /usr). I do not use a boot
loader either, I use CONFIG_EFI_STUB=y and compile in the command
line arguments to avoid trouble. Then, I use efibootmgr to boot the
kernel at /boot/EFI/Gentoo/bootx64.efi
I usually keep several kernels in the same directory with a version
suffix (e.g. bootx64-4.6.2.efi, etc) and overwrite the bootx64.efi
file with whatever kernel I want to boot with cp bootx64{-4.x.x,}.efi
I keep a few older kernels around in case I screw up the configuration
of a new one (usually video drivers), but for the most part, that's it.
My compiled kernel command line is also pretty simple:
quiet console=tty1 root=/dev/sda4 init=/usr/lib/systemd/systemd
I never really though about writing scripts to manage this, since it's
quite a simple setup, but having tools to manage it would be nice.
Just think about supporting a simple EFI/UEFI setup, I would say, in
addition to the more common setups using a boot loader.
