Fedora 18: Install with LVM on RAID 1

[Guido Winkelmann]

Hi,

How can I make the Fedora installer install the OS in Logical Volumes that lie 
on top of a RAID 1 MD-device?

I have some fairly specific ideas about how I want my harddisk space used, 
which previous versions of Fedora would allow with no problems:

sda1 -> /boot

sda2 \
      -> md0 -> PV -> VG -> various different system LVs
sdb2 /

sda3 \
      -> md1 -> used directly as data partition
sdb3 /

sda5 -> another data partition

sdb5 -> another data partition

The parts below md0 are not so important, I can easily add those manually 
after the system is installed and up and running (provided the installer will 
graciously leave me some unpartitioned space on my hds - another aspect that 
seems needlessly hard to control with the new partitioning tool). However, the 
parts on md0 really need to be supported by the installer itself, because 
that's where the actual OS is installed, and I just cannot seem to figure out 
how to make it do it this way. All it ever seems to do is collect all the 
available unpartitioned hd space on all selected hds and combine it into one 
large Volume Group...
