You quoted me completely out of context! The only advantage of
linux-only partitioning *over a raid-style superblock* is that
a linux partition table would be able to describe multiple devices
at once, whereas a raid md0 superblock only describes a single
logical device. LVM lets you provide UUIDs for multiple logical
devices in a single partition.
The LVM superblock is exactly what you are after, isn't it? You
place one of those on a DOS partition, and then you can carve off
fixed-name portions by allocating physical extents from the LVM
pool to specific logical volumes. We don't need to discard the
existing, portable partitioning mechanisms in order to achieve this.
