[Testbed-admins] Customizing Generic Image

[Timothy Ficarra <t.ficarra@yahoo.com>]

In the customizing generic image tutorial is this command:

sudo ssh pc1 imageunzip - /dev/$DSK \
  < /usr/testbed/images/$FULL-GENERIC.ndz

I am curious if the dash is a typo. I ran the command today, and it idled for about two hours before I finally canceled it. If I run the command without the dash I receive:
WARNING: output file is not seekable, must zero-fill free space
Bad Magic Number!
