I completed my LFS-6.7 and now doing BLFS build. Now while going through the book BLFS-6.3 in chapter no. 3 there are lot of operations to adjust Bash Shell Startup Files.

I am not clear about what type of user a developer should be while performing those operations. While logged in as a non-priviledged user one can't alter the bash files. And in the case of root login I am confused which root to be used??
The root of already built lfs (having its home directory as /mnt/lfs)
(chroot "$LFS" /usr/bin/env -i \
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
/bin/bash --login
)
OR
The root of the host system which I am using for the build??
(chroot "$LFS" /tools/bin/env -i \
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
/tools/bin/bash --login +h
)
Please guide me

BLFS-6.3 used for the build
Ubuntu-10.04 used as host

Ideally you would boot into your completed LFS system (you know, restart the machine) and then start BLFS. Thus, you should be the root user on the new LFS system to do BLFS.

Sir but how could I read the BLFS book side by side and the most important I wouldn't be able to connect to the internet as I use WLAN???? :-(
And all the operations shouldn't be done as the root user This is mentioned in the book

Hi

As you asked about chapter3 this is done as root, when installing packages that is when you are user lfs to configure and make them and then as root to install.
As you copy and paste you could copy the commands on a machine with internet connection 1stthen read them when booted into lfs/blfs.
Install GPM and 1 of the text web browsers 1st lynx or links.
It would be easier to have a wired connection at 1st rather tan wireless as there is abit of work involved in getting wireless working.
