UDisks

UDisks, formerly DeviceKit is a system that allows handling of storage devices. UDisks usually relies on kernel udev rules, but devices that don't have udev rules are polled.

UDisks provides access to block devices via D-Bus. This is why devices are mounted at session specific directories like /run/media/<username>/<device-id>.

Udisks consists of a D-Bus daemon udisksd and a command line shell udisksctl.

Access to UDisks can be restricted using Polkit.

Some frontends for udisks2 are:

• GNOME Disks
• udiskie
