It's nearly impossible. If we do that we'll have to introduce at least five
new
packages: dosfstools, popt, pciutils, efivar, and efibootmgr. Pciutils is
recommended to be installed along with "which" (it's a package's name), and
one
of wget/curl/lynx to make update-pciids script usable. And, to make grub
menu
"showing normal" we'll need freetype. Freetype has a circular dependency
with
harfbuzz. Harfbuzz requires glib, graphite, and ICU to be fully functional.
Worth pointing out, as the hint does, that you can install Freetype
without the harfbuzz, so as to get enough to install an enhanced
Grub, and then go back and install a Freetype+harfbuzz later.
That's my approach, and OK for a hint.
Another way: provide a binary unicode.pf2 file on Anduin, and skip freetype.
It's just a font and it's not a problem not to build a font "from scratch".
Similarly, the lack of an update-pciids script may not be a major
problem as, when building the UEFI-aware Grub for the first time,
you can download what that script would fetch, using the host
system, and just put the payload into place on the LFS system.
The problem is we have to defer the activation of update-usbids.timer (for
systemd) or cron job (for sysv) after wget/curl/lynx is installed. Then where
should we put the instruction? Not a technical problem but a book structure
issue.
It's probably way too far beyond LFS to have it in the LFS Book,
but the basic capabilities are not as hard to add as one might
come to think, just by following all of the BLFS Book's dependencies
to the end of each chain.
I think it might be better to put EFI grub and its dependencies into BLFS. There
is BLFS #5379 (opened 6 years ago). If Bruce agrees I'll change the milestone
to 10.1 (10.0 will be too hurry) and do it. And, William Harrington suggested
that LFS should support some non-x86 architectures, which would require
different bootloaders. They can be put into a new BLFS chapter "alternative
bootloaders", along with EFI grub.
If you can maintain it on an ongoing basis, I'm OK with adding a section
on bootloaders in 10.1. I went ahead and added a 10.1 milestone to BLFS.
When you are ready, we can discuss where it should go in the book.
