#130513 remove 130509, code now in init script in initrd.
#130513 init in initrd creates /root/.xorgwizard-reenter, need to ask kbd/locale even though auto-X at 1st boot...

#130629 need directory /tmp/pup_event_ipc, to support new pup_event IPC.
#130630 bring back tmpfs on /tmp for full HD installation.
