Nuther Newbie here,

host: live cd 6.2.5
book: 6.2
addition resource: LFS hints; install-lfs-from-livecd.txt

http://www.linuxfromscratch.org/hint...rom-livecd.txt

I understand the purpose of lsfchroot.sh in the hints file, but I'm a little confused about why the the difference between the LFS book and LFS Livecd hints in the sections 6.2.2 and 6.2.3.

book;
mount --bind /dev $LFS/dev
mount -vt devpts devpts $LFS/dev/pts
mount -vt tmpfs shm $LFS/dev/shm
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys

LiveCD hints lsfchroot.sh script (partial-clipped);
mount -t proc proc $LFS/proc
mount -t sysfs sysfs $LFS/sys
mount -f -t ramfs ramfs $LFS/dev
mount -f -t tmpfs tmpfs $LFS/dev/shm
mount -f -t devpts -o gid=4,mode=620 devpts $LFS/dev/pts

Can anyone offer any clarification?

well, a good question:
what version of the liveCD are you working with?
[ assuming you are working with the book as currently posted on the lfs website ]

part of the differences could be to version differences between the cd and the book as posted on the website.

a bigger role would be that the livecd os is all in ram, you have to alter the procedure slightly from using an installed host system, in order to actually chroot to the build system. as a ram only os, the livecd pointers are session based, causing the requirement of uing the proc system to change the root of the system to the under construction os on the hardware.

Thanks. Sorry for taking so long to get back to you. I'm using version 6.2.5 of the live CD, and yes it was the current book as of about a month ago.
Rather than using the scripts, I've gone ahead and used the hibernate feature, storing the current session to swap, as no other OS uses this hardrive. Seems to be working OK as I crawl through the book, learning the stuff I probably already should have known.

purely FYI, I use the live CD with generous use of console mouse cut and paste, using;
shell 1: lynx and the html format of the book.
shell 2: system command prompt and man pages
shell 3: working environment ie: $LFS
