udisks v2 removeu a opção "ocultar" (embora "ignorar" possa ser uma espécie de semelhante) e renomeou os outros. De acordo com a página de manual udisks(8) :
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.
