Just install usbmount, and you can just put your scripts in
/etc/usbmount/mount.d/ -- they get passed the mountpoint as an envvar
:-) We use it on the XS to great effect.

What James points out however is important. All of this runs as root.
A trickster can make a rather instructive mess.

In addition to James' example, keep in mind that the network
configuration files are actually executed as shellscripts. So
/etc/sysconfig/network-scripts/ifup-eth0 can state that IP_ADDR="`rm
-fr /`" and it will run it, expecting that the comand prints out
something to assign to the IP_ADDR variable.

Don't try it. It doesn't :-)
