Debian Installation :: Preseed Hostname Reconfiguration

I'm trying to create preseed configuration for debian. Currently I'm working with Debian version: 7 (wheezy), Installer build: 20130613+deb7u2+b1.

What I want to achieve is to have different network configuration than during installation.

I have two preseed files, one in intrd and the second that is fetched through http (url argument to kernel)

In the initrd file there are settings required to get dhcp network settings that will be used during installation:

Code: Select alld-i netcfg/choose_interface select auto
d-i netcfg/get_hostname string unassigned-hostname
d-i netcfg/get_domain string unassigned-domain

Then in the preseed file that is downloaded from network i have this:

Code: Select alld-i netcfg/choose_interface select auto
d-i netcfg/disable_autoconfig boolean true

d-i netcfg/get_ipaddress string 192.168.56.199
d-i netcfg/get_netmask string 255.255.255.0

[Code] ....

IP address settings work as expected, at the end of the installation netcfg runs again and when installed system boots it has static address set (.199). However hostname stays the same, it is not reconfigured.

I have tried many different combinations like removing get_hostname and get_domain options form initrd preseed and appending 'priority=critical' to kernel boot arguments but no matter what I do it always fails.

Is there any way to do this? I know that hostname can be set by hostname= krenel boot arg or by using dhcp option but I'd like to avoid this.
