The automounter facility is managed by autofs. ”Autofs controls the operation of the automount daemons. The automount daemons automatically mount filesystems when they are used and unmount them after a period of inactivity. This is done based on a set of pre-configured maps

apt-get update
apt-get install autofs


insert stick
dmesg

add this line to 
nano /etc/auto.master
/var/autofs/removable   /etc/auto.removable --timeout=2


Where:

    * /var/autofs/removable is the directory where will be mounted your USB stick
    * /etc/auto.removable is another file that we have to create
    * –timeout=2 tells that the device will be umounted them after 2 seconds of idling 


nano /etc/auto.removable
usbstick	-fstype=vfat,rw,umask=002	:/dev/sda

/etc/init.d/autofs restart

cd /var/autofs/removable

/var/autofs/removable# ls

/var/autofs/removable# ls usbstick

does not work for me
