Heh.. I should have checked mails more often while coding ;-) This is what I got, which is slightly different from your series because I want to call set_git_dir() just one time (by setup_git_directory) and never again. I think the API looks close enough. I will probably rework on top of your chdir-notify instead (and let yours to be merged earlier) Note, this one is built on a strange base, which is a merge of 'next' and 'sb/object-store' (I needed 'next' and Junio would have another evil merge if 'sb/object-store' was not in the base).
