Not really. The LFS scripts are spartan, but functional. The idea
behind the BLFS scripts is to give you some suggestions to use.

Exactly. They are meant for you to select and choose. For instance is
says explicitly in the introductory paragraph to extra-prompt.sh
"This script shows an example of a different way of setting the prompt."
It is meant as an example. Most people don't use it. There has been
some discussion about removing or modifying this section.

Right. Leaving root's history file around is a security issue. That
behavior is controlled by:
if [ $EUID -eq 0 ] ; then
pathappend /sbin:/usr/sbin
unset HISTFILE
fi
If you don't like it, just remove the unset command.
