I found that "chroot" can only be run by root. Why cannot it be run as a
normal user?
From the Wikipedia page on chroot:
"Only the root user can perform a chroot. This is intended to prevent
users from putting a setuid program inside a specially-crafted chroot
jail (for example, with a fake /etc/passwd file) that would fool it
into giving out privileges. It also, however, prevents non-root users
from using the chroot mechanism to create sandboxes of their own."
Also see the schroot package.

I do not put /home on a separate partition because I never know how much
space I need for personal files and how much space I need for system
files. If I have another physical disk, I'd rather put backups on it.
I used to have that problem. But then I learnt about lvm and I now set
it up everytime, even on single disk systems, so that I have the
flexibility of being able to resize everything later.
