[CUWiN-Dev] dhcpselect error

Sat Jul 23 11:25:55 CDT 2005

I'm not sure when this broke, but we've found that on new builds that 
dhcpd isn't starting for standalone nodes.  After checking the dhcpselect 
debug log (see attached) and code, the problem was in the 
pack-master-iface() function when not providing the 3rd argument (wedge 
setting).

The attached patch fixed things here.  I also removed the DHCPSELECT_DEBUG 
definition so it could be set in the environment.
