I hosed up with vi

[Walter]

Hi, all.  Attempting to install from CD, I apparently
hosed up doing the "disklabel -e" probably because
of my inexperience with vi.  The problem I created
was a "disk full" error.  (I have 80MB RAM on that
computer.)  I was not able to continue or quit from
vi, and when I did ctrl-alt-del, there was a stream
of "disk full" messages.  I had to hit the power
button to reboot.  I realize I messed up, but I think
the error handling is not doing what it should.
