There is currently an odd behaviour when locally cloning a repository with symlinks at .git/objects: using --no-hardlinks all symlinks are dereferenced but without it, Git will try to hardlink the files with the link() function, which has an OS-specific behaviour on symlinks. On OSX and NetBSD, it creates a hardlink to the file pointed by the symlink whilst on GNU/Linux, it creates a hardlink to the symlink itself. On Manjaro GNU/Linux: $ touch a $ ln -s a b $ link b c $ ls -li a b c 155 [...] a 156 [...] b -> a 156 [...] c -> a But on NetBSD: $ ls -li a b c 2609160 [...] a 2609164 [...] b -> a 2609160 [...] c It's not good to have the result of a local clone to be OS-dependent and besides that, the current behaviour on GNU/Linux may result in broken symlinks. So let's standardize this by making the hardlinks always point to dereferenced paths, instead of the symlinks themselves. Also, add tests for symlinked files at .git/objects/. Note: Git won't create symlinks at .git/objects itself, but it's better to handle this case and be friendly with users who manually create them.
