New option DISK_FOLLOW_SYMLINKS
If DISK_FOLLOW_SYMLINKS=yes then for any disk image paths that are a
symlink, follow the symlink when creating the image.
This allows disk images to be reorganised, perhaps across several
disks, and replaced with symlinks. On the next cluster creation the
symlinks will be respected and the layout of disk images will be
maintained.
