Aaron:
We had a long argument (or discussion) about Linux and CD RW disks. In
short Linux does not in general allow one to use CD-RWs in his way.
Pehaps Rex was (almost) right.
I found this on http://fedoraproject.org/wiki/FedoraLiveCD :
* Read-write rootfs so it's possible to install software while the
livecd is running.
But, I read someone's paraphrased version, which mentioned 'RW
filesystem' - which I understood as CD-RW.
