[ILUG] dump+restore of linux system

[Walter Faleiro]

Hi Conor,
using the -x option did not help at all. restore man pages say the file
sytem where the data restore is taking place should be pristine. so I guess
I can restore it to a different partition and have grub boot from that
partition.
My issue is how to simulate it in vmware. There should be posting surely for
this and will dig vmware site for the same.
thanks,
--Walter
