I didn't resurrect the thread, by almost the same name, from last
November because of some miscues back then and I think I've moved to a
more detailed and successful position. But I'd be more than happy to
dredge up that thread or move this to blfs-support. The discussion I'd
like to generate falls in that finely narrow gap between LFS and BLFS.
And this post will probably be a little long.
I've gotten LFS-7.5 to boot from both gummiboot and, more interestingly,
from GRUB in Ubuntu. Last year I was unable to do the latter. My goal
is to get GRUB working from the EFI partition and have the OS, in this
case HP, boot manager default to my GRUB-lfs-7.5. Additionally, I do
not want to copy every kernel to the EFI partition. I want those
kernels to reside in $(root)/boot. I booted 7.5 this way from Ubuntu's
grub, and if I want to keep Ubuntu around, I need go no further. But
I'd like to do this so that I can share the procedure here--and, yes,
until Apple writes a linux version of iTunes, I want to be able to boot
to Windows too.
It may not seem like it, but doing this is just, well, maybe almost,
like installing GRUB to a boot partition, except that in this case the
boot partition is called EFI Partition and is vfat instead of ext{3,4}.
But I've reached a knowledge impasse. The first one generated when I
built GRUB in Ch. 6. I accidentally discovered that GRUB, before I
installed it was built for i386 and none of the efi options I specified
were configured. I discovered and used the switches:
--target=x86_64
--with-platform=efi
I learned these from both the ARCH and Ubuntu wiki's. Neither
explanation nor help with these appeared in <./configure --help> or in
the GRUB Manual. The GRUB info file is the GRUB Manual.
I'd like to find some *good* documentation that discusses the options
for various GRUB building concepts; e.g., ./configure and grub-mkimage.
Like I said, I can find these things on sites like ARCH and Ubuntu, but
I've not found anything that describes the uses of these various
switches. Does anyone know of any documentation like that. If there's
a book, I'll go buy it.
In particular when I built GRUB, /boot/grub was not created. This
surprised me when I discovered it. I don't know if the above two
configuration switches has anything to do with it, and I have no way of
finding out. My logs are silent on the issue.
One possibility, at least install-grub wants to make sure that the
module EFIVARS is loaded. The kernel documentation says, and has said
since 3.10.10, that this module is no longer used and efivarfs is used.
I do have that configured and mounted. I suppose I could re-configure
my kernel and include that module to see if it breaks anything.
I'm hoping that someone who monitors this list will be able to answer or
at least point me in the right direction for resolving the documentation
and the kernel things.
Thanks,
Dan
