Current BusyBox configuration

Setting a DHCP hostname in /etc/network/interfaces like this

--8><--
auto eth0
iface eth0 inet dhcp
  hostname myhostname
--><8--

results in the following warning when starting up the network interfaces:

--8><--
[...]
udhcpc: option -h NAME is deprecated, use -x hostname:NAME
udhcpc (v1.23.1) started
[...]
--><8--

The script /etc/init.d/networking (from Poky 1.8) is using ifup, so there seems to be an BusyBox-internal incompatibility between these two tools.
