Actually, he is quite correct. /mnt/cdrom is a directory located off of /mnt which in turn is located off of /. Until you mount a cdrom in which case /mnt/cdrom actually starts pointing to the /dev/cdrom device which is then the size of whatever media is mounted. Experiment: As root, with no cd mounted, cp a file to /mnt/cdrom and you will note that the file is copied and then exists in /mnt/cdrom. Clearly with no media mounted, it can not be stored on /dev/cdrom but the directory does exist independent of the device as long as no device is mounted. You can also open up konqueror as root and navigate to /mnt and then check properties on /mnt/cdrom and it will show you how much space is available on root. > Turgut is correct -- /mnt/cdrom is on the CD drive which is not the same > device as / is on. Only after a cd is mounted, until then it is a directory called /mnt/cdrom which is stored off of /. -- Bryan Phinney Software Test Engineer
