Detailed Description
LVM provides very little benefit for most Fedora users, at the cost of performance and complexity:


 * Certain filesystem features (ext3 barriers) are unavailable when run on top of LVM.
 * This is one of the root causes of the Firefox 3 hangups with
 * Software RAID performance is greatly reduced when layered on LVM.
 * LVM partitions are not automatically assembled by the desktop systems.

Benefit to Fedora
New Fedora installs will not use LVM unless specifically requested - experts in storage administration can still set up volumes however they like.

Scope

 * Patch anaconda to change the default partition layout:
 * /boot on the first available disk
 * / expands to fill the largest available disk
 * But what do we do with the rest of the disks? - Maybe we should use LVM only for system with more than one disk?
