[edit] 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

- 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.
[edit] Benefit to Fedora
