Linux: LVM Fix duplicate VG names with vgrename uuid, a device filter, or system IDs.

Během přenášení dat mezi dvěma disky může najít ke kolizi VG names. V mém případě se to stalo, když jsem vyměnil v PC původní disk za nový a pak se snažil data z nového překopírovat na ten nový, takže poměrně častá situace...
