[Hardy alpha5] network configuration alteration on update

release : Ubuntu Hardy alpha5

Bug occurs when updating a fresh and clean install of Ubuntu Hardy alpha5 with 03/03/2008 updates (sources.list has not been modified).
This bug prevents me from using my wireless connection after the update (usbcore : zd1211rw, ID 079b:004a Sagem).

before update "more /etc/network/interfaces" return :
___________________________
auto lo
iface lo inet loopback

auto eth1
iface eth1 inet static
address 192.168.1.4
netmask 255.255.255.0
gateway 192.168.1.1
wireless-key *************
wireless-essid ********
___________________________

after update :
___________________________
auto lo
iface lo inet loopback

                                                <- someone is missing ^^
iface eth1 inet static
address 192.168.1.4
netmask 255.255.255.0
gateway 192.168.1.1
wireless-key *************
wireless-essid ********
___________________________

adding "auto eth1" solves the problem.

Hope this help, G
