Just for clarification, are we talking here about:

#1 Potentially deprecating ovirt_init param in favor of storage_vol
fancier syntax
#2 Going from solely having ROOTDRIVE and HOSTVGDRIVE, to any number of
devices, since for each LV you'd be allowed to specify a different one
#3 Going from solely having HostVG VG, to any number of VGs, since for
each LV you'd be allowed to specify a different one.
