I will upgrade to 1.0.6 and see if there are any changes

LVM did not do what I wanted, it failed. On a new install it still see's
a full device physical volume from a previous install. My new install
has only one physical volume on a partition. It fails because vgscan can
not find any volume groups because pvscan is looking for the now
non-existent physical volume on the entire disk.
