    This sounds like a recipe for disaster to me. What if the user's device
    has a weird directory structure, a weird filesystem, or only 500K free?
    Most automated processes like the ones you describe must make a large
    number of assumptions, and if their assumptions aren't correct, they
    tend to fail in interesting and stupid ways. (Been There, Done That,

    /etc/hotplug/ should contain a bunch of files that have a bunch of
    comments in them. On my Gentoo system, /etc/hotplug/usb/usbcam is a
    shell script that executes when a USB camera that matches a large list of
    device IDs is plugged in. This script just does a chmod/chown to the
    camera's device node so the currently-logged-in user can do stuff, but
    it could be rearranged to do other things. "man 8 hotplug" may also
    provide info on the guts of the hotplug system. HTH,
