Yeah, the host that you're building on (what is it, and what version?) might be
calling your partitions /dev/hda.., but the lfs (what version is it you're
building?) is likely calling them /dev/sda.. . So the /etc/fstab that you're
creating for the lfs side of things, would need to use the 'dev/sda..' naming
rather than the '/dev/hda..' naming.

/dev/hda.. or /dev/sda.. ?
For the grub config for the lfs side, looks like you're OK wrt device naming:
i.e.
use the form 'hd0' for the 'set root=(hd0,...)' line, and use the form
'/dev/sda..'
for the 'linux /boot/vmlinu... /dev/sda.. ro' line that is contain within
'menuentry' sections.
'vmlinux' -vs- 'vmlinuz': as another poster has noted, be clear which one of
these you want to be referring to: from the host that you're using to build
lfs,
what does '\ls -laF ${LFS}/boot' show? If you've got a 'vmlinux...' then use
that
for grub; else use 'vmlinuz...' .
(( Yes, the kernel page 'chapter08/kernel.html' for lfs 7.3, 7.2, ... _does_
talk about 'vmlinux...' in the section at the foot of the page; and
'vmlinuz...'
elsewhere in the page and in the grub section.
