Well I have a cleaner way actually that I used previously, which is to
use a ROOTFS_POST_BUILD build script that clones the repository and
'rsync' it on the target rootfs, I was mainly wondering if I could
achieve the same using the ROOTFS_OVERLAY feature. It seems it's not
enough for my needs, so I will actually stick to my previous
ROOTFS_POST_BUILD script and forget about ROOTFS_OVERLAY.

Thanks for your hints anyway, and keep up the good work everybody.
