[ipxe-devel] script failure caused by adding one line

[Robin Smidsrød]

You can use the syslog console (http://ipxe.org/console) in combination
with DEBUG=script, which should allow you to get the debug information
in your syslog, which is easier to trap during runtime.

Also, you might want this iseq line:

iseq ${vodserver} 6 && set bu http://10.109.0.165/ ||

If the iseq returns false I believe it will abort the script without the
|| at the end.

Michael: Correct me if I'm wrong.
