Re: [Testbed-admins] Customizing Generic Image

[Mike Hibler <mike@flux.utah.edu>]

Just to make sure there is no misunderstanding: on your boss node you should
be running:

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

where $DSK and $FULL are set apprpriately on boss?  The key is that imageunzip
be run on the node but the redirection of input comes from a file on boss.
Like you say, it is behaving as though it is waiting for input, as though
the redirect were not happening

If you just do:

  sudo ssh pc1 id

does it return output?

Run "imagedump" on the image file on boss just to make sure there is nothing
wrong with the image.  Then try adding a couple of -d options to the imageunzip:

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

and see if you get any output.
