	Check if the uid of root is 0. (See below)

	Try lilo: linux emergency to get in. Then remount root rw.
Make a link of /bin/bash to /bin/sh or some other shell if bash doesn't
exist.

	Did a little digging. The above message comes from wall() which is
called in shutdown.c

	uid = getuid();
        if ((pwd = getpwuid(uid)) == (struct passwd *)0 &&
            (uid != 0 || fromshutdown)) {
            fprintf(stderr, "You don't exist. Go away.\n");
            exit(1);
        }
Since here, fromshutdown is 1, it must be that getpwuid(uid) is
returning NULL.
	maybe the uid of root is not 0, and there is no user with uid 0

	Best of Luck... and Enjoy Life...
