Instead of changing VFS you can probably make a generic stackable FS module
.....that can stack on top of the physical filesystems and happily take
snapshots at "FS" level :) ! and you can use the FIST to create a basic
stackable FS and then modify it to take care of snapshoting ! ( the good part
is it can work on scores of other OSs like solaris , freeBSD etc )
i created one for ext2 but then it was not genric enough to work for other FS
!
cheers,
