Vagrant chicken-and-egg: Shared folder with uid = apache user

If you can fix the uid/gid values you can use these in the mount command – they don’t have to relate to an existing user/group

I do this with a user that is later created by puppet using fixed (matching)uid / gid values

config.vm.synced_folder "foo", "/var/www/foo",
   id: "foo", :mount_options => ["uid=510,gid=510"]
