If, for whatever reason, console access is not appropriate for you, and you need to give non-root users access to your system's diskette drive, this can be done using the floppy group. Simply add the user(s) to the floppy group using the tool of your choice. Here's an example showing how gpasswd can be used to add user fred to the floppy group:

[root@bigdog root]# gpasswd -a fred floppy
Adding user fred to group floppy
[root@bigdog root]#

User fred will now be able to access the system's diskette drive (using the mtools utility programs, for instance).
