Is it possible to do this at install time?

For example, I currently kickstart install my xen guests as follows:

xenguest-install.py --name=guest1 --file=/dev/vg01/lv_guest1_vm
--ram=384 --location=http://mirrors.kernel.org/fedora/core/5/i386/os/
--extra-args="ip=192.168.23.229 netmask=255.255.255.248
gateway=192.168.23.225 dns=192.168.2.203,192.168.2.204
ks=http://dev.robinbowes.com/kickstart/misc/guest1-fc5.cfg";

The disk layout is defined in the kickstart config.

But I'd need to specify that /dev/vg01/lv_guest1_root = /dev/sda1,
/dev/vg01/lv_guest1_usr = /dev/sda2, etc.

Is this possible with xenguest-install.py or do I need to use a
different install method?

Thanks,

R.
