[vox-tech] How much free space on CD?

How do you determine how much free space is left on a CD (or 
equivalently how much has been written already?)

df tells me only the size of the last session (and always reports 0 free 
space in a CDs partition)

du would be useful in most circumstance. In this particular circumstance 
it doesn't since, I'm using the -root and -old-root options of mkisofs 
to burn the CDs so the CD has something equivalent to hardlinks. One 
quirk of this is that none of the inode numbers are the same, so they 
don't look like hardlinks to du, and the result is essentially the same 
as being forced to use "du -l" on the CD.

Any ideas?
