An iterator, which yields the absolute paths (including the device

UDev can create symlinks to the original device node (see

used to assign a constant, fixed device node to devices like
removeable media, which technically do not have a constant device
node, or to map a single device into multiple device hierarchies.
The property provides access to all such symbolic links, which were
created by UDev for this device.
