DOC: lack of clarity on folder ownership.
Make this [/hxdepots/sdp] directory writable - to whom? And what are the full permissions? Does it need to be owned by 'p4admin' or (if you're using the script default) 'perforce'?
Is this not handled by the mkdirs script alongside the other /hx directories?
UPDATE: reopened - the SDP Guide still states "make the entire $SDP directory writable" but doesn't clarify ownership, nor if this is handled by the mkdirs script.
