Setting permissions on /mnt

["shrevie@ntnation.com" <shrevie@ntnation.com>]

I have a Debian Linux Sid system that has a compactflash slot, setup to 
mount CF cards on /mnt/flash.

I mount them from the commandline, just doing something like this:

mount -t vfat /dev/hdg1 /mnt/flash

When mounted, the filesystem is read-only (which is what I want), but is 
owned by root (I can't execute mount except as root).

However, I want a non-root user to be able to access it.... and even as 
root, I can't change the perms on /mnt/flash after mounting.

What am I doing wrong? Basically, I just want /mnt/flash to be 
accessible (read-only) by other users on the system.... but I can't 
figure out how to o this (chown and chgrp don't allow me to do it -- 
probably because its read-only).

Any ideas?

Thanks!
