I thought it was the /boot partition that couldn't be part of a volume
group.
I've never had much luck searching the archives. Do you have a link?
The /boot partition can not be part of a volume group, since GRUB
can't read Logical Volumes. You make a lot of difficulty for yourself
if you make the / (root) partition part of a volume group, since you
have effectively blocked yourself from resizing that partiton except
by running from a RAMdisk with the original root partition not
mounted.
The default Fedora installation puts /boot as a physical partition,
and then puts all of the rest of the disk as one volume group,
divided into two logical volumes, swap and root. This is fine until
you want to take advantage of LVM and change the partitioning scheme.
