Preseeding a Debian Jessie doesn't yield a default gateway

I used this in the .seed file: d-i netcfg/choose_interface select eth0 d-i netcfg/get_hostname string fj4.testnet d-i netcfg/disable_autoconfig boolean true d-i netcfg/dhcp_failed note d-i netcfg/dhcp_options select Configure network manually d-i netcfg/get_ipaddress string 10.201.0.34 d-i netcfg/get_netmask string 255.255.0.0 d-i netcfg/get_gateway string 10.201.0.1 d-i netcfg/get_nameservers string 10.206.0.11 d-i netcfg/confirm_static boolean true which I use (adapted, with cobbler) and the installed system does have the correct ip address and netmask, but no gateway directive in the /etc/network/interfaces file. What am I missing?
