lots of references have to be kept and passed around because once the device is removed Solid::Device is just an UDI - anything else is obtained dynamically and will return invalid results (even casts will not work) what the mountpoint cleaner does? when a device is removed without being unmounted (e.g. USB storage) the program will call `unmount` essentially making sure the device node and the mount point can be used when the device is inserted again, no other project does that as far as I am aware Signed-off-by: Ivailo Monev <xakepa10@gmail.com>
