Did you try using busybox dhcp client on an already installed system, as opposed to the debian installer? I just tried - dnsmasq as dhcp server, and squeeze busybox - it accepts the /32 netmask just fine and configures the interface accordingly. I had to overwrite "netmask" option on the server, setting it explicitly, and I verified with tcpdump that the server sends correct DHCP reply with the right netmask. But I'm not actually sure how debian installer configures the network... Thanks, /mjt -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
