That's probably because you mean to be looking for "supermount
" and not "automount".
It's very unlikely that there's a whole site about auto-mounting, since the whole process consists of adding the "auto" option to the line in /etc/fstab which mounts the CD-ROM, so that it mounts on boot. Other than that, if the CD has to be changed, the drive has to be unmounted and remounted manually. man mount and man fstab have the best information on mount options available.
On the other hand, supermount
is a kernel function which allows you to mount the drive "transparently", so that it mounts automatically, and you can remove and change the media inside normally (meaning by using the eject button and simply changing the media), without having to unmount and remount the drive.
Some readme's and how-tos about this include:
You might also be referring to autofs
(but probably are not, as autofs is not recommended for removable media drives). Here's a page about that:
Hope this helps answer your question.
