Yes.  Possibly even users.  The reason should be in either
the /etc/fstab tutorial or, within it, is a link to mounting with the
mount command.

1. insert a cd into the cd drive prior to bootup.  That is where the
auto and user(s) are put into use and the script will mount your cdrom.
The message about "only root..." is because, if the cd is not mounted
during bootup, then the cli requires that only root can mount.  NOTE:
cli = command line interface, typing commands at the prompt.

To do a mount of your cd at the command line prompt,if you are not using
the script, do the following:
grasshopper at linux:~> su
type on this line root's password.  NOTE you will not see anything when
you enter the password.

The prompt changes from > to # which indicates that the current user is
now root.

/home/root at linux:~># mount /dev/cdrom
/home/root at linux:~># ls -l /dev/cdrom

You should now see the files on your cdrom.

Enter 
/home/root at linux:# exit
grasshopper at linux:~>
You are now not root but your user and you can then copy files from your
cdrom.
