Then every symlink to an annexed object uses a relative symlink via this: `.git_annex/objects/xx/yy/ZZZZZZZZZZ`. Even though this symlink is relative, moving it to a different directory would not break anything: if the move destination directory already contained other annexed data, it would also already contain `.git-annex` so git-annex wouldn't need to do anything. And if it didn't, git-annex would simply create a new `.git-annex` symlink there. + +These `.git-annex` symlinks could either be added to `.gitignore`, or manually/automatically checked in to the current branch - I'm not sure which would be best. There's also the option of using multiple levels of indirection: + + foo/bar/baz/.git-annex -> ../.git-annex + foo/bar/.git-annex -> ../.git-annex + foo/.git-annex -> ../.git-annex + .git-annex -> .git/annex + +I'm not sure whether this would bring any advantages. It might bring a performance hit due to the kernel having to traverse more symlinks, but without benchmarking it's difficult to say how much. I'd expect it only to be an issue with a large number of deep directory trees. +"""]] |
