Subject: [PATCH] Relocate the nbroot to /opt/xcat/share/netboot -Override init
 with our own in order to preserve control of PID 1 (for switch_root) -Change
 nbroot shell to actually call shell and loop, rather than exit since that
 would be init trying to exit now -Increase destiny retrieval interval a bit
 to be less harsh, don't background as this must continue to be PID 1
