I would not advise either of the above plans. This is yet another
problem with boot-from-volume.
A better use of your time would be to split the original giant volume
into the operating system part and the application data part. Make the
application data part into a normal non-bootable volume and use a
regular operating system image as your root/boot partition.
You can't build a palace on quicksand.
