For the menu install, just don't choose partitioning and use local install
directly - that will just overwrite the node image on existing disk
partitions.

For autoinstall disk is currently always reformatted, to allow disk reusage,
I'll modify ovirt_init parameter like follows:

 ovirt_init=[usb|scsi[:serial#]|reuse|/dev/...]
 # local installation target disk
 # usb|scsi - select disk type, as reported by udev ID_BUS
 # serial# - select exact disk using serial number, as reported by
 #           udev ID_SERIAL
 # reuse - use existing partitions, fails if they don't
 # /dev/... - use specified disk device (for cases when HAL doesn't handle
it)
 # empty value - grab the first disk (/dev/?da)
