DEVICE INFORMATION 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_CAN_POWER_OFF If set, this overrides the value of the CanPowerOff 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[5]. This corresponds to the HintIconName property. UDISKS_SYMBOLIC_ICON_NAME The icon to use for the device when presenting it in an user interface using a symbolic icon. If set, the name must adhere to the freedesktop.org icon theme specification[5]. This corresponds to the HintSymbolicIconName property. UDISKS_FILESYSTEM_SHARED If set to 1, the filesystem on the device will be mounted in a shared directory (e.g. /media/VolumeName) instead of a private directory (e.g. /run/media/$USER/VolumeName) when the Filesystem.Mount() method is handled.
