of=/dev/sdb
> bs=4096
> conv=notrunc,noerror" will accomplish the cloning (sda and sdb are of
the

> 3.  Do I have to do anything post-cloning to make sdb bootable?
> 4.  What rsync command would I use to keep the two disks synced?

> If anyone has gone through this process, and can provide guidance, I'd
