At the moment all modifications are installed in RAM and lost after reboot.
When you ask "to the disk", do you mean the CDR disk? The very nature of a CDR/CDROM disc implies that it is difficult (more like impossible) to write to the disc, especially if the disc is 695MB or 700MB. If it was possible to write another track or another session to a CDR, there would still be the issue of UnionFS mounting this data on top of the existsing UnionFS mount. In theory it sounds as if it can be done but as with many things, the devil is in the details/implementation.

When you ask "to the disk", do you mean the hard disk? If so, then it should be much easier to create a place to store the data. The it would be up to the user to figure out how to UnionFS mount the stored data on top of the existsing UnionFS mount.

Please see my post in this thread here http://www.knoppix.net/forum/viewtop...?p=78447#78447. It details how Knoppix creates the UnionFS mounts on bootup.
