Take a look at git-clone or ln documentation sometime, you might understand what I meant by concept
.
git clone is able to exploit hard links as part of cloning repositories through the file system rather then the network, as a way to save disk space and time used; chosen, I assume for the same reason that FreeBSD uses hardlinks instead of symlinks to create programs with multiple names pointing to one binary (like ex, vi, nex, and nvi).
Being able to apply the same concept as a hard link, automagically at a lower level then whole files [sic], is a good thing :-D.
