boot is not included on the LV because bootloaders don't
understand LVM volumes yet. It's possible boot on LVM will
work, but you run the risk of having an unbootable system.

<para>
root on LVM requires an initrd image that activates the root
LV. If a kernel is upgraded without building the necessary
initrd image, that kernel will be unbootable. Newer
distributions support lvm in their mkinitrd scripts as well
as their packaged initrd images, so this becomes less of an
issue over time.

When she hits a similar problem she can reduce the size of /home by
a gigabyte and add that space to the root partition.
