[rescue] Imaging Solaris 2.5 without SCSI devices

Thanks Carl.

I have a nice Origin 200 running as an NFS server here, and I was
going to try that.

Mostly what I'm worried about is DDing a mounted, running, volume.

Is this something that should be attempted from single user mode or similar?

Namely worried about filesystem integrity and locks.

I'm concerned because I have no good way of verifying the integrity of
the image without wiping the drive, due to simple lack of hardware.
