I suspect you have erased the /root directory. To verify, as any user, do a 'cd /' and then do a 'ls -l' and see if you still have the root directory.

I'm not sure how to recreate it, if it is gone. Possibly someone else can chime in and help out. Post back what you find.

Standard incantation when you screw something up and can't log in as root (this assumes you are "local" and have physical access to the machine, of course, if it's a remote system, you'll need someone on hand to do it for you):

Reboot, at the lilo/grub boot screen, append 'init=/bin/sh' to the command line. This will boot you straight into a shell (at this point, you are, by definition, root, since the shell is running as init (process 1)). Then, remount / read-write:

Fix whatever it is you screwed up (details vary... ).

Now, remount ro:

Finally, exec init to continue booting normally:

(No need to reboot.)
