10.1. Upgrading to LVM 1.0.8 with a non-LVM root partition
10.2. Upgrading to LVM 1.0.8 with an LVM root partition and initrd

Transitioning from previous versions of LVM to LVM 1.0.8 should be fairly painless. We have come up with a method to read in PV version 1 metadata (LVM 0.9.1 Beta7 and earlier) as well as PV version 2 metadata (LVM 0.9.1 Beta8 and LVM 1.0).

Warning: New PVs initialized with LVM 1.0.8 are created with the PV version 1 on-disk structure. This means that LVM 0.9.1 Beta8 and LVM 1.0 cannot read or use PVs created with 1.0.8.
