Some other issue arises:
1. pax '-M norm', this option isn't support by my RHEL-distributed pax. Shall I
simply omit it? or use '-t' substitute it? I tried the latter, seems working.
2. I initially run build-amd64 job, it will firstly re-install host, that's 
right. But after
it is installed, it restarts host and again jump into a manual off-on loop.
Do you know which part of code is controlling this?
