How to automatically execute a command (TrueCrypt) on mount
 

Simply that : I would like to make my Ubuntu automatically execute some script when my USB token is mounted.

I'm already using udev to create a /dev/myusbkey device, so it's always mounted at the same place (let's say /media/myusbkey) in the filesystem.

What would be the most convenient / portable / easy way to do it ?

Note : I would use this to automatically mount the TrueCrypt volume on my usb key when mounted, so if you have a better idea for this specific need...

TrueCrypt sounds like an encoded/encrypted FS ... do you need to use
a password/passphrase to get to it?

Yes it's an encoded fs and I need to type a password to get it mounted.

Since the fs is actually a file on my usb token (FAT), the token has first to be mounted and only then I can mount the encoded file as a volume using the 'truecrypt' command

Two steps on my Ubuntu.

If only I knew a way to trigger an arbitrary command on an USB insertion event, I could do it in one step.
