allowing non root users to mount

Thank you for your reply.
I don't understand how editing /etc/fbtab will help me provide a
mounting point that is accessible to everyone. I believe that fbtab will
just set the permissions of the device to whatever is specified in that
For example, if I have the following in the /etc/fbtab file:
/dev/ttyV0 0700 /dev/fd0
then upon login, the floppy device (/dev/fd0) will have the permission:
So, how does this relate to making a common mounting point? I want to
make the common mounting point /floppy and set the permissions to
rwxrwxrwx by doing a 'chmod 777 /floppy' but for some reason I still
cannot mount the floppy as a regular user. It keeps on telling me that
'operation not permitted' and I have to su as root to get this to work.
Why is this so? Shouldn't it be okay since I've set the permission of
/floppy to be accessible to anyone?

Right. You want that for security reasons.

Make the common mount point accessible to the console user. fbtab(5)
(or xdm's 'GiveConsole' script, etc.) will help here.
