 After looking at the name you use for your email account, I have to
ask "why don't you just run everything as root ? - it will make it
much easier for people to own your system" ;-)  I'm joking, but I
start to wonder if you are trolling.

 For a safer system, limiting privileges is a good idea.  To shut
down a *desktop* box, I'm happy using a hack to let a user run
'shutdown' - but I'm the only user of those machines, and I can
only run the user shutdown script from a tty (not an xterm, nor when
using ssh to connect to a system).  Some other people use 'sudo' and
allow (some) normal users to shutdown, others run desktop
environments where ConsoleKit gives permissions to whoever is at the
physical machine.  Every alternative method has its own advantages
an disadvantages.

 Also, the /tools part of the PATH should be unnecessary after you
have completed chapter 6 of LFS.  If you need to go back in to
chroot to edit some files, chroot /mnt/lfs should work fine - if it
doesn't, you've got other problems.  In any case, why would you
prefer to run the programs from /tools/sbin in preference to /sbin
or /usr/sbin ? - hint: a program will be run from the first
directory which contains a program of that name.

das eine Mal als Tragödie, dieses Mal als Farce
