NAME
       udisks - storage management

DESCRIPTION
       udisks provides an interface to enumerate and perform operations on
       storage devices. Any application can access the udisksd(8) daemon via
       the name org.freedesktop.UDisks2 on the system message bus. Some
       operations (such as formatting disks etc.) are restricted using
       polkit(8).

ACCESS CONTROL
       By default, logged-in users in active log-in sessions are permitted to
       mount and unlock devices attached to the local console. To lock down
       globally, configure the polkit(8) authorizations for the actions
       filesystem-mount, filesystem-mount-system, encrypted-unlock and
       encrypted-unlock-system, all in the org.freedesktop.udisks2 namespace.

       Note that the actions ending in -system typically requires
       administrator authentication and are used for devices not considered
       "removable" (devices considered "removable" include USB attached
       storage, Flash media, optical discs etc.). The udev property
       UDISKS_SYSTEM can be used to override this on a per-device basis, see
       below.

       To lock down access on a per-device basis, use the option x-udisks-auth
       in the /etc/fstab file and the option x-udisks-auth in the
       /etc/crypttab file.

DEVICE INFORMATION
       On Linux, udisks relies on recent versions of udev(7) and the Linux
       kernel. Influential device properties in the udev database include:

       UDISKS_SYSTEM
	   If set, this overrides the value of the HintSystem property.

       UDISKS_IGNORE
	   If set, this overrides the value of the HintIgnore property.

       UDISKS_AUTO
	   If set, this overrides the value of the HintAuto property.

       UDISKS_NAME
	   The name to use for the device when presenting it in an user
	   interface. This corresponds to the HintName property.

       UDISKS_ICON_NAME
	   The icon to use for the device when presenting it in an user
	   interface. If set, the name must adhere to the freedesktop.org icon
	   theme specification[1]. This corresponds to the HintIconName
	   property.

       For media and drive identification, the output of the probers supplied
       by udev(7) (such as cdrom_id, ata_id and scsi_id) are used in addition
       to the following properties:

       ID_DRIVE_THUMB
	   The device is a thumb-drive with non-removable media (e.g. a USB
	   stick).

       ID_DRIVE_FLASH
	   The device is compatible with flash.

       ID_DRIVE_FLASH_CF
	   The device is compatible with Compact Flash.

       ID_DRIVE_FLASH_MS
	   The device is compatible with Memory Stick.

       ID_DRIVE_FLASH_SM
	   The device is compatible with SmartMedia.

       ID_DRIVE_FLASH_SD
	   The device is compatible with SecureDigital.

       ID_DRIVE_FLASH_SDHC
	   The device is compatible with High-Capacity SecureDigital.

       ID_DRIVE_FLASH_SDXC
	   The device is compatible with Extended-Capacity SecureDigital.

       ID_DRIVE_FLASH_MMC
	   The device is compatible with MultiMediaCard.

       ID_DRIVE_FLOPPY
	   The device is compatible with floppy disk.

       ID_DRIVE_FLOPPY_ZIP
	   The device is compatible with Zip.

       ID_DRIVE_FLOPPY_JAZ
	   The device is compatible with Jaz.

       While the ID_DRIVE_* properties describe what kind of media the drive
       accepts (more than one property can be set) and correspond to the
       MediaCompatibility property, the ID_DRIVE_MEDIA_* properties describe
       the current media in a device (typically only one of these properties
       are set) and correspond to the Media property:

       ID_DRIVE_MEDIA_FLASH
	   The physical media currently inserted into the device is flash.

       ID_DRIVE_MEDIA_FLASH_CF
	   The physical media currently inserted into the device is Compact
	   Flash.

       ID_DRIVE_MEDIA_FLASH_MS
	   The physical media currently inserted into the device is Memory
	   Stick.

       ID_DRIVE_MEDIA_FLASH_SM
	   The physical media currently inserted into the device is
	   SmartMedia.

       ID_DRIVE_MEDIA_FLASH_SD
	   The physical media currently inserted into the device is
	   SecureDigital.

       ID_DRIVE_MEDIA_FLASH_SDHC
	   The physical media currently inserted into the device is
	   High-Capacity SecureDigital.

       ID_DRIVE_MEDIA_FLASH_SDXC
	   The physical media currently inserted into the device is
	   Extended-Capacity SecureDigital.

       ID_DRIVE_MEDIA_FLASH_MMC
	   The physical media currently inserted into the device is
	   MultiMediaCard.

       ID_DRIVE_MEDIA_FLOPPY
	   The physical media currently inserted into the device is floppy
	   disk.

       ID_DRIVE_MEDIA_FLOPPY_ZIP
	   The physical media currently inserted into the device is Zip.

       ID_DRIVE_MEDIA_FLOPPY_JAZ
	   The physical media currently inserted into the device is Jaz.
