AIX had a clever way of integrating their LVM with boot. There was a specially
marked boot LV that was required to have exactly one extent, and was not
allowed to move (without updating the boot code). The "boot" flag
caused the userspace tools to prevent operations that might leave the
system unbootable.
This reduces LVM to the equivalent of a partition as far as the
boot code is concerned.
