Following the advice of akhiezer in his note from 18-May-2017, I'm going
back to try to install LFS stable version 8.0, in order to gradually work
up to installing LFS systemd development version with LVM, LABEL/UUID in
fstab, intramfs, etc.
However, I'm getting conceptually stuck at how to boot with my EFI
motherboard (Asus TUF Mark 1), using the lfs-uefi.txt hint mentioned in
the LFS
book, ch. 8.4.1.
Note that my host Fedora is on /dev/sda, and I'm putting LFS on
/dev/sdd. Other hard disks contain incomplete experiments, with /dev/sdc
containing
an incomplete systemd.

####
MOUNT EFI PARTITION
Determine which device is the EFI partition using gdisk or
parted,
enter the chroot environment, create /boot/efi if needed, and
mount -vt vfat /dev/sda(x) /boot/efi
where sda(x) is the device containing the EFI partition.
####
Two sticking points:
1. I assume that with my present setup, I should use /dev/sdd rather
than /dev/sda, because I DON'T want to change the Fedora boot stuff.
Rather, I
want to be able to boot directly from the LFS disk. Ultimately, I want
to use a boot manage like RodsBooks' rEFTnd (which I successfully installed
on /dev/sdb). And if I remove all disks, but /dev/sdd, I want to boot
directly from that.
2. Do I use the LFS book's instructions on partitioning a strictly MBR
boot setup, or make GPT partitions? See the information and discussion
below.
To let you see my setup, I've gotten some info on my setup from various
disk commands.
The difference between a stricly MBR partition scheme and a GPT scheme
can be seen in the outputs from the following info commands, executed in the
LFS chroot or Fedora host environment as needed. Note that I'm inserting
some comments for clarification:

Here is my first cut at /etc/fstab for systemd on /dev/sdc:
######
[root@localhost rootlfs1]# cat etc/fstab
# Begin /etc/fstab
# file system mount-point type options dump fsck
# order
/dev/sdc4 / ext4 defaults 1 1
/dev/sdc3 /boot ext4 defaults 1 2
/dev/sdc1 /boot/efi vfat defaults 0 2
/dev/sdc5 /opt ext4 defaults 1 2
/dev/sdc6 /home ext4 defaults 1 2
/dev/sdc2 swap swap pri=1 0 0
######
Here is my first cut at /etc/fstab for non-systemd on /dev/sdd:
######
root:/sources# cat /etc/fstab
# Begin /etc/fstab
# file system mount-point type options dump fsck
# order
/dev/sdd3 / ext4 defaults 1 1
/dev/sdd1 /boot ext4 defaults 1 2
/dev/sdd5 /opt ext4 defaults 1 2
/dev/sdd6 /home ext4 defaults 1 2
/dev/sdd2 swap swap pri=1 0 0

tmpfs /run tmpfs defaults 0 0
devtmpfs /dev devtmpfs mode=0755,nosuid 0 0
# End /etc/fstab
######
Given the above and the discussion of having a /boot/efi vfat partition
in the
hints, I'm thinking that the /dev/sdd fstab should be this:
######
...
/dev/sdd5 / ext4 defaults 1 1
/dev/sdd3 /boot ext4 defaults 1 2
/dev/sdd1 /boot/efi vfat defaults 0 2
/dev/sdd6 /opt ext4 defaults 1 2
/dev/sdd7 /home ext4 defaults 1 2
/dev/sdd2 swap swap pri=1 0 0
...
######
Note that /dev/sdd4 would be the MBR extended partition.
While I wait for some advice, I'll be installing the extra software
required by the hints.
Question: has anyone on the LFS staff besides the authors (Dan McGhee,
Kevin M. Buckley) gone through all this? I'm happy to be a guinea pig,
because I'm learning a lot.
