notes of fedora experience for ISO mounting :
[root@localhost /]#umount /mnt/cdrom
mount:can't find /mnt/cdrom in /etc/fstab or /etc/mtab
[root@localhost /]#mount -t iso9669 -0 loop xxx.iso
mount: can't find xxx.iso in /etc/fstab or etc/mtab
[root@localhost /]#mount /dev/device /mnt/xxx.iso
mount: you must specify the filesystem type
got mad...
[root@localhost /]#mount /dev/cdrom /mnt/cdrom
mount:block device /dev/cdrom is write-protected,mounting read-only
dev--properties -- permissions -- file access -- read and write
[root@localhost /]#mount /dev/cdrom /mnt/cdrom
[root@localhost /]#
