Secure is a function of how you export your system. You export by the remote system, so, no export, no problem :). I have used it to recover systems. I had a mobo go and when I loaded the HDs, I had a pair switched. It was immediately obvious but some links seemed to go by-by. I brought the recovery system up todate and loaded the kernel and world on the sick system. After the upgrade, I had no more problems. I remounted the ../src and ../obj from the sick machine and went on with business. Kent -- Kent Stewart Richland, WA http://users.owt.com/kstewart/index.html
