These days I use a few working trees that are connected to my
primary repository (which also has a working tree).  The primary
repository is in /src/git, and other ones look like this:

: gitster git.wk0; ls -l .git/
total 120
drwxrwsr-x  3 junio src  4096 Mar  5 16:22 ./
drwxrwsr-x 15 junio src 16384 Mar  5 16:23 ../
-rw-rw-r--  1 junio src    41 Mar  5 16:22 HEAD
lrwxrwxrwx  1 junio src    27 Mar  3 22:53 config -> /src/git/.git/config
lrwxrwxrwx  1 junio src    26 Mar  3 22:53 hooks -> /src/git/.git/hooks/
-rw-rw-r--  1 junio src 82455 Mar  5 16:22 index
lrwxrwxrwx  1 junio src    25 Mar  3 22:53 info -> /src/git/.git/info/
drwxrwsr-x  3 junio src  4096 Mar  3 22:59 logs/
lrwxrwxrwx  1 junio src    28 Mar  3 22:53 objects -> /src/git/.git/objects/
lrwxrwxrwx  1 junio src    32 Mar  3 22:53 packed-refs -> /src/git/.git/packed-refs
lrwxrwxrwx  1 junio src    25 Mar  3 22:53 refs -> /src/git/.git/refs/
lrwxrwxrwx  1 junio src    28 Mar  3 22:53 remotes -> /src/git/.git/remotes/
lrwxrwxrwx  1 junio src    29 Mar  3 22:53 rr-cache -> /src/git/.git/rr-cache/

It shares everything other than HEAD and the index (the reflog
for branches are also shared by a symlink .git/logs/refs
pointing at the one in the primary repository).

This risks confusion for an uninitiated if you update a ref that
is checked out in another working tree, but modulo that caveat
it works reasonably well.

We might want to add an option to 'git-clone' to create
something like this, but I am somewhat worried about the newbie
confusion factor.  Perhaps...

$ git clone --i-know-what-i-am-doing-give-me-an-alternate-working-tree \
  /src/git /src/git.wk0
