I saw https://stackoverflow.com/questions/200960/find-all-storage-devices-attached-to-a-linux-machine#201091 and while that is cool, I am/was wondering if it can be similarly achieved by using udisksctl. It should as the help gives enough indication -[$] udisksctl helpUsage:  udisksctl COMMANDCommands:  help            Shows this information  info            Shows information about an object  dump            Shows information about all objects  status          Shows high-level status  monitor         Monitor changes to objects  mount           Mount a filesystem  unmount         Unmount a filesystem  unlock          Unlock an encrypted device  lock            Lock an encrypted device  loop-setup      Set-up a loop device  loop-delete     Delete a loop device  power-off       Safely power off a drive  smart-simulate  Set SMART data for a driveUse udisksctl COMMAND --help to get help on each command.Using [$] udisksctl status /dev/sddoes give you list of all hard disks, pen-drives/SSD's etc but not partitions. Any ideas ? 
Is there a way to ask udisksctl to list all partitions and block devices?
