ex/vi: Error: Log file: No such file or directory (solved)

[Jed Clear]

For the record[1]:

After a non OS drive hardware[2] failure I started getting the following
when trying to vi a file as a non root user:

	ex/vi: Error: Log file: No such file or directory

I spent time chasing a few other things since chunks of /var and /etc
were also missing[3].  However, I was ultimately forced to use the
source, Luke.  What I found was that my non root account had $TMPDIR set
to a directory that was on the defunct disk.
