Are you comparing pre- and post-diest-upgrade? Re-adding the two etho lines should fix it all for you - unless a reboot deletes them, somehow! If it happened via the dist-upgrade (and not via debconf), grepping "/var/lib/dpkg/info/*" for "/etc/network/interfaces" might give you the culprit; most likely the ifupdown scripts in there. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
