Actully, the original intention was to find a quick way to checkout and
build several projects regularly. The first thing came to me was cloning
shallow repos for saving some time. So I tried it with my local repo first.

Later, one of my co-works suggested me to try git archive, and that did
reallly fit my needs.

Thanks for clarifying my confusion.
