Creating an ISO from a CD on Linux

As many can relate too I've built up a huge pile of CDs from customer PC builds, PC installs, software purchases, etc. Now that I've migrated my main PC over to Linux I wanted to move all of them out to ISOs so I'd have a backup (plus I'm working on automated offsite backups). Doing it is easy!

dd if=/dev/cdrom of=cd.iso # for cdrom
