This looks strange to me. It acts like we need mkfs the directory before
run the sheep, where as we actually make nothing to it, just create a
file lock. This extra step might solve some problems (which could be
solved by other means), but it will cause great inconvenience to all
users: we have to run sheep with sheep -i for the first time, and for
following restarting, we don't need it.

Thanks,
