Any ports that download whole trees with git?

Fetching over VCS without generating intermediate distfile would bypass
our mirroring infrastructure. Also, the package cluster uses distfile
cache to speed up build on many release/architecture combinations.

To maintain consistency in distfile naming/contents and help yourself
snapshot generation is probably better be automated. See devel/llvm-devel
or www/calendarserver as examples though they're for subversion.

Keep in mind such a service should generate distfile with consistent
checksum. It's not rare when checksum varies due to volatile timestamps
of the files within (e.g. android.googlesource.com).

GitHub is well-supported, so creating a mirror there can be an option if
you have nowhere to host a snapshot. You'd only need to sync or re-create
the mirror when updating the port.
