If allows you to have /usr on a volume manager, LVM of ZFS, without the
extra work of putting / on there. / doesn't really need to be on LVM/ZFS
since its size is unlikely to change much.

However, the main reason, IMO, for not putting root on the volume manager
is to avoid the use of an initramfs. If it's going to require it anyway,
you may as well use the initramfs to put / on the same managed volume
as /usr. That's the route I took a while ago, using an initramfs to avoid
having a separate /usr.

On the eudev vs. udev point: Dale, if you read flameyes's blog post,
you'll see that this isn't just about udev.
