The work tree is the place where your checked out files reside. E.g.,
in an ordinary repo (made with "git init" or "git clone") everything
that isn't in the .git directory.
$ cd /www/mysitedocroot
$ git --git-dir /gitdir/mysitegit/ add .
fatal: add must be run in a work tree
You are using --git-dir to point to a repository directory that isn't
".git". That's OK, and it will generally assume that your current
directory is the work tree. E.g., this works:
mkdir repo && cd repo
git init
mv .git mygitdir
touch file
git --git-dir=mygitdir add file
However, there is a config option "core.bare" which indicates that a
repository is "bare", meaning that it has no work tree (and that is
presumably what's happening in your example). So you could use
--work-tree=. to override that in your example (though you might just be
better off setting config.bare to false).
The more probable use case for --work-tree is something like
$ cd /gitdir/mysitegit
$ git --work-tree=/www/mysitedocroot add .
i.e., you are in the git dir, so you specify the work tree rather than
the other way around. You could even do this:
$ cd /some/other/directory
$ git --git-dir=/gitdir/mysitegit --work-tree=/www/mysitedocroot add .
although I'm not sure it's that useful.

Yes, thanks, I was actually following this tutorial:
http://www.kernel.org/pub/software/scm/git/docs/cvs-migration.html
Which is how I ended up with a "bare" git dir. Which actually I think
I'm ok with, seems to work ok.
For others with the same questions, here's how I found what work-tree
means last night:
http://www.kernel.org/pub/software/scm/git/docs/glossary.html
I think I got there through the git wiki.
Also- I found out I needed a newish version of git to get the
--work-tree argument. The CentOS repos have an older version, 1.2.something.
thanks
