Presumably the benefit is that you can shuffle storage from one
partition to another with relative ease, if your initial choice of
partition sizes was wrong.
Partition that _must_ be excluded from LVM: /boot
Partition that _should_ be excluded from LVM: /
Because it is damned difficult to resize a mounted root partition.
Default FC3 installer puts boot in its own partition, and all the rest
of the disk becomes one LVM Logical Group, with two Volumes in it,
root and swap. Nobody wants this.
I also discovered the hard way that an LVM file system can be crashed
by a power failure, in such a way that I couldn't find any tools to
recover it. Fortunately, what I lost was a data partition, with about
30GB of assorted things downloaded from the net, and maybe 5GB of
backups that also exist on DATs.
