Upstart calling script (for inserted USB-drive)

Question

I know that Ubuntu (and Fedora) uses Upstart istead of the classical System V init daemon (SysVinit).

I would like to know how to detect when a USB-drive has been insert

Answer 1

In Ubuntu 9.10 and newer Upstart has some udev capabilities through the upstart-udev-bridge service.

#thumbdrive_special.conf
start on block-device-added

task

script
   if [ `blkid $DEV` -eq "YOUR-THUMBDRIVES-UUID" ]; then
      /home/you/bin/thumbdrive_special $DEV
   fi
end script

I love how simple and elegant upstart can be. However, a DBus solution might be better if less elegant. With a DBus solution you could pop up notifications to the user and provide easy user control.
