As I already pointed out, re-establishing the correct privilege
isolation is a fundamental step to enforce security, even though the
phone will have only 1 user. In the future we should have a few root
process, dedicated accounts for daemons and a X session belonging to
the user. IMHO it could be a good idea to suppress root account and to
take full advantage of PAM+SUDO facility.
