Not an ISO9660 Filesystem, the CD default.  The filesystem was simply 
designed for a Write Once media, and was optimized under the assumption 
there would be no random writes.

However, there is no rule that a CD must be ISO9660..

You can format a CD ISO udf (see udftools), which has random write 

And if Windows/MAC compatibility is not an issue, you can put whatever 
filesystem on an ISO you want, including creating a ext3 image file that 
  will later be burned to a disc.
