udiskie is a simple daemon that uses udisks to automatically mount removable storage devices.
udiskie requires permission for the org.freedesktop.udisks.filesystem-mount action. This is usually granted in sessions launched with ConsoleKit support. If run outside a desktop manager with ConsoleKit support, the permission can be granted using PolicyKit by creating a file called 10-udiskie.pkla in /etc/polkit-1/localauthority/50-local.d with these contents:
[udiskie] Identity=unix-group:storage Action=org.freedesktop.udisks.filesystem-mount ResultAny=yes
This configuration allows all members of the storage group to run udiskie.
