Yup.   It is in /usr/bin
I guess, I am so used to putting a copy of vi in /bin shortly after
installing a new system that I assume it is always there.

Anyway, in this poster's situation it should be possible to also
do:

  fsck -p /usr
  mount /usr

in addition to the other things mentioned and then 'vi' and some
of the others would be available - but not things that need services
running.
