    appliance: init: properly set PS1 and TERM for virt-rescue (RHBZ#812970).
    
    Setting environment variables such as PS1 for bash before starting it
    might not be effective when the startup scripts provided by the
    distribution unconditionally change it.
    Hence, set PS1 and TERM in a ~/.bashrc, which will be source'd last and
    thus be able to set them the way we want.
