Howto install "18" on RAID0->LVM->ext4->root FS??

view full story

http://forums.fedoraforum.org – I have preexistent storage layout: RAID0 with LVM volume inside. A kind of incapsulation: HDDx2 -> RAID0 -> LVM volume -> ext4 partition -> root filesystem mount point. Is there any way to install Fedora 18 using such a layout? It is great, if there is any opportunity to install using already created (by my own script) partitioning and not to create the partitions with the help of Anaconda. (HowTos)
