Now that I've gotten jhalfs to (seemingly) build OK, I'm trying to
get LFS systemd to boot up. So far, no cigar.
Last month I built systemd through Linux-5.4.13 and got it to boot,
but now, using similar boot techniques, I can't get Linux-5.5.3 to
boot. I'm beginning to suspect that there is a difference between
the 5.4.13 and 5.5.3 kernels.
For different "linux ..." lines in grub.cfg, I get the same response
when I try to boot: I get a "grub > " screen and can not do anything
further. I think the grub command line interface is well nigh
useless, by the way.
So here is my grub.cfg:
##############
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod gzio
insmod part_gpt
insmod ext2
# From blkid:

997d-c503b15520e8"
insmod efi_gop
insmod efi_uga
insmod font
if loadfont /grub/fonts/unicode.pf2; then
loadfont /grub/fonts/unicode.pf2
set gfxmode=auto
insmod gfxterm
set gfxpayload=keep
terminal_output gfxterm

I built initrd.img-5.5.3 using the BLFS instructions.
I followed the instructions in the LFS hint
http://www.linuxfromscratch.org/hints/downloads/files/lfs-uefi.txt
to install much of the software, with some modifications.

I'm trying to get systemd working with LVM and UEFI, so I've had to
figure out how to get this far with not much help from the LFS
documentation. Any comments on this will be appreciated.
Note that my goal here is not to *some* LFS system running, since
good instructions from LFS already exist for that, but to learn as
much as possible by solving problems such as the above.
As usual, thanks for your help!
