This works for the CD-ROM drive after doing "chgroup audio /dev/cdrom;
chgroup audio /dev/hdc" as root (should I have done that?) but doing "mount
/dev/fd0 /floppy" as a user still gets "mount: only root can do that":
$ mount /dev/fd0 /floppy/
mount: only root can do that
$ ls -l /dev/fd0
brw-rw---- 1 root floppy 2, 0 May 27 1997 /dev/fd0
$ groups
m dialout floppy audio dip
