Well, that depends on how you want to write to it. Keep in mind that when
you add and remove files from a filesystem, directories need to be updated.
How do you update a directory structure in a filesystem on write-once
media. The answer: you don't. There are devices out there that support
updating filesystems on WO media, but they usually "throw away" a directory
structure and create a new one when you change the contents of a directory.
The "throw away" space is wasted.
If I were going to do this, I would write to the CDROM as a raw device.
First byte of log entries at byte 0 of the CDROM. Don't put a filesystem
on it. It would be seekable much like looking through a file.
