Do you know of any major distributions using this mechanism? I’ve only ever seen GRUB on UEFI.

- rl3 8y agoArch supports it: https://wiki.archlinux.org/index.php/EFISTUB https://wiki.archlinux.org/index.php/EFISTUB Being able to directly edit your motherboard's EFI boot order via command line is admittedly pretty neat. That said, using a traditional bootloader seems to be a popular choice still for simplicity and portability reasons. EFISTUB also can make certain crypto setups more difficult as far as I'm aware.
- checkyoursudo 8y agoOn Gentoo, for a couple of years, I used an initramfs compiled into the kernel to boot via EFI_STUB with full disk encryption. It's possible. It's been a while. I don't remember it being very easy to wrangle. I don't use that laptop anymore, but I still boot via EFI_STUB on my desktop. It's super simple to set up when you're not using FDE. I don't remember there being any specific problem that make some crypto setups more difficult than others, with the caveat that implementing FDE at all makes EFI_STUB somewhat more complicated no matter what. Like I said, it's been a couple of years since I figured all that stuff out, so the passage of time may have softened the terror of configuration and clouded my memories.
- rl3 8y ago>... the terror of configuration ... That's an excellent way of phrasing it.
- checkyoursudo 8y agoI have been booting an EFI_STUB kernel in Gentoo for several years. It's pretty easy to do. See, e.g., https://wiki.gentoo.org/wiki/EFI_stub_kernel https://wiki.gentoo.org/wiki/EFI_stub_kernel
