Solaris provides vold (Volume Management Daemon) which lets you deal easily with removable media such as CDs and DVDs.
This tool is provided by the SUNWvolr and SUNWvolu packages. Once you have found those packages and installed them, accessing to your removable medias becomes a bliss : All you have to do is insert your media, and go in the configured directory (ex : /cdrom).
Those directories are defined in /etc/vold.conf.
NB : maybe you’ll need to mkdir /vol, and maybe you’ll have to manually enable the service (svcadm enable volfs) the first time (and preferably in this order).
