beta2 ongoing development

udhcpc had issues with some wlan sticks drivers, couldn't obtain dhcp address. full isc package was ok with wlan, but if installed, ifup is configuring even static interface ages (5+ seconds). so I let uninstall them both and based on udhcp rewritten the networking.

tested on my install was ok, then tested on clean beta1 upgrade and clean beta1.1 upgrade. plus tested with three different sticks and was ok. so I pushed to you. and it looks you are like magnet for bugs, so it's good you testing

ifconfig eth0 up is just making interface available. it will not configure it. and if you specify address, it will confiure it, but will not setup default gw. that's why you can not access internet. this has to be done with "iproute add default gw x.x.x.x". if you change interface to static in network/interfaces, it needs address net mask and gateway as well. if you have it there "ifup eth0" will do "ifconfig eth0 up; configure ip through 'ip' and set routing". this is something I didn't touch, so it muss work (regardless of any *dhcp* package in the system).

if you set dhcp, ifup will do the first part (eth0 up), then it will look for dhclient binary, or dhclient3 binary or finally for udhcpc binary (or script). then it will call it with and ask for DHCP iface configuration - where the workflow should start.

I will turn debug logging in the scripts, can you then reinstall xbian-update package ?
