Maybe. Or maybe because when that computer's hard drive starts getting full and you add a new hard drive, if you're using lvm with a few commands you can make your /home expand across both drives, while with straight partitions that is a lot more work. There really is no reason not to use some kind of volume management solution these days, whether that is zfs/btrfs, or lvm. When your data is on lvm it is MUCH easier to move it around than if you just put it directly on drive partitions. Arguably you want more flexibility around adding/removing drives on the desktop than in the enterprise, because desktop users don't add and remove drives in sets of 5-6. This is why I think btrfs is actually superior to zfs conceptually on the desktop (setting aside the fact that it will tend to eat your data) - the flexibility matters more on the small scale because you want to go from a 3-disk RAID5 to a 4-disk RAID5. -- Rich
