To summarize the referenced email: PS1 is unset by non-interactive bash 
shells, so setting PS1 only at login means it is not inherited by interactive 
shells which have a non-interactive shell in their ancestry.

Attached is a patch for base-files which attempts to fix this by moving the 
PS1 initialization from /etc/profile to /etc/bash.bashrc and moving the hook 
which runs /etc/bash.bashrc from ~/.bash_profile to ~/.bashrc.

This affects the prompt displayed in an xterm in the default configuration.

You can also demonstrate the change by comparing the behaviour of 'bash -c bash'.
