One method is to check /etc/debian_chroot.  This will only exist
inside the chroot.  In fact, the bash shell automatically reads this
and adds it to the prompt:

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, overwrite the one in /etc/profile)
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

It should be equally easy to set this for other shells.

We could certainly add such an environment variable.
