Environment variables in .git/config -

i have git repo created --serparate-git-dir option. use same repo form different working trees specifying --git-dir , --work-tree arguments.

i have 2 working trees switch between added .git file in secondary work tree pointing repository directory. since repository's config file points primary working tree, still have specify explicitly, otherwise uses primary working tree.

i tried setting value of worktree $pwd int .git/config file causes following error: fatal: not chdir '$pwd': no such file or directory

is there way make worktree dynamic?

edit 05-2016 @amynbe comments, git >= 2.5 has git-worktree https://git-scm.com/docs/git-worktree

i have script on freenode passed around, i'm not sure of author know can share, used create different working copyes based on branches, think fit use case:
