or A)

A) seems cleaner.

wrt C):

- I have tried p9fs before and it is not so easy to make it work
  correctly, because you cannot get the uid mapping between host and vm
  correct all the time; it's "easy" to get it working if the share is
  read-only from the PoV of the VM, but not so easy otherwise.

- rsync seems like a terrible regression on how vagrant is supposed to
  work. you expect to change something from the host and it being
  immediately reflected on the VM, but when sharing via rsync you need
  to re-provision the VM to have your changes reflected, which sucks
