Hey there,
As far as I know there isn't something like this in FreeBSD. However,
please find attached a short c program written by Omachonu Ogali that
allows normal users to mount the cdrom (you can obviously modify it to
mount the floppy as well). To install it, simply do the following: (as
root)
cc -o sucd sucd.c
chmod 4555 sucd
mv sucd /usr/local/bin
What you're doing there is setting the binary as setuid which allows
people to execute it as root, and allows them to mount/unmount the CD.
Hope this helps.
Cheers,
Marc
