To change the prompt you want to set $PS1. For example:
echo 'export PS1="some string"; exec </dev/tty' | exec chroot $ROOT
/bin/bash -i
This command tells the Bash inside the chroot to first execute
export PS1="some string"
and then to continue as a regular log-in shell. The special syntax of
the $PS1 string in described in the Bash man page. If you just want to
prepend a string, you do not even have to bother with crafting a syntax:
echo 'export PS1="(chroot '$HOST') $PS1"; exec <dev/tty' | exec chroot
$ROOT /bin/bash -i

Bas
