Yes. Most strange I can't log in as root or "su" I have just upgraded to slink from hamm. Everything went pretty well, for some reason sash became my shell for root? (probably me using dselect - iused the multicd method. well not Knowing 
sash (well not at all axcept that its pretty powewrful, i've logged out root bye typing "exit" which dropped me back to a console login prompt (so far so good )BUT....now i cant login as root! i can log in as any user but NO-ROOT! i keep 
getting a quick messabe saying "su:cannot execute exit no file or directory" then it just 
drops me back to the ansci login prompt?? it seems like a danferous feature
