Pleasre reply to me directly, since I'm not subscribed to the mailing list.
I will post a summary if requested.

We are considering to replace our current CD burning s/w (GEAR on a Solaris
2.5 system) with mkisofs/cdrecord. We plan to do the move as soon as we
upgrade the machine from Solaris 2.5 to Solaris 2.7 (the alternative would be
to get a new license for GEAR).

My question is the following. Can I copy sparse files or at least multiple
separate directory tree in an image using mkisofs, similar to the
functionality we had in GEAR

We have not retrieved any tar file yet, but I have checked the (too extensive)
material on
http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html
but can't find an example in the man pages corresponding to what I mean.

All examples are : one Unix directory tree -> one CD.

For instance with GEAR I used the following commands to copy several
directories (but not the entire /poseidon tree) on a CD

NEWVOL AUG00A 74 ISO
cp -r /poseidon/iau .
cp -r /poseidon/login .
cp -r /poseidon/nospam .
cp -r /poseidon/ntlucio .
cp -r /poseidon/lucio .

I also had more complex cases (in general I tend to pack as much data as one
can on a CD, and therefore when I have large data directories I have to split
things like : directory A and two subdir of directory B on one CD, and
the rest of directory B and directories C and D on another, this way using two
CDs instead of three or four.

Can this be done with mkisofs, and how (or where is it written) ?
