CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS was set to '-n' which means
"Exit with failure if lease cannot be immediately negotiated."
What we'd rather want is for udhcpc to continue to run until a lease can
finally obtain. Otherwise we have a race condition in case the DHCP
server is not reachable for a few seconds during system boot, and end up
having a system that is permanently without an IP address.
This fixes ORT#639
Make sure that there is at least a basic depmod in the image. This
is needed as fallback for kernel upgrades that execute depmod in the
postinst script. The dora busybox will always have it so we should
have it too. Sync the defconfig with dora.
