Just wondering if there is a way to increase the length of time that dhcpd
looks for an IP address? We have a problem with spanning tree causing
network port initialization delays, and therefore ZEN imaging clients cannot
get IP addresses thru DHCP. The fix is to enable portfast on the affected
network ports, but I was hoping we could also modify a conf file somewhere
to make dhcpd wait longer (?).

I am testing with the BootCD, not PXE.
