We are running Xenix V here, and Xenix V uses /.profile before $HOME/.profile
only when starting the top-level single-user-mode sh.  I have placed:

			SU_MODE=1; export SU_MODE

in /.profile only, so I can always determine if I am in single user mode just
by examining "$SU_MODE".  If your system lets you determine if you are in
single user mode during the shell startup script then you can use this too.
