Hi all,
In startscript "target/default/target_skeleton/etc/init.d/S50dnsmasq", there is a problem with the execution of the udhcpc script when running. It tries to execute /dev/zero, which is not a valid script. Changing the script to /bin/true works much better:

--- target/default/target_skeleton/etc/init.d/S50dnsmasq        25 Jun 2005 06:38:42 -0000      1.5.2.1

I'll change it, but the point was simply to test for a dhcp server. The script specified really makes no difference as we have no intention of actually using the IP given; the IP is immediately released.

The discussion might have continued from here.
