The RW and RO volumes share the same inodes (for the data part) as long a=
they're on the same partition and the RW volume has not been altered sinc=
releasing the volume. The space needed for the second volume header shoul=
neglegtable. That's as far as I know -- please correct me if I'm wrong.

yeah, but you were going to delete it anyways, weren't you? So the worst =
would be that the users mount the RW volume, delete the data and fill it =
with other data -- which they can not rely on since it will be deleted w/=
further notice a couple of days later. In this case you'll indeed end up =
twice the disk space used for a short period of time. I don't think that =
should be much of an issue in the days of Terabyte disks, shouldn't it? ;=
