6. config-store doesn't save info on non-attached devices (ones without a
node)
Even if I create a device and then set some attributes on them they still
get ignored if they are not assigned to a node. Now, this might be working
as intended, but I've a reason why this might be a good feature to have. If
you are constructing a simulation of some nodes communicating you can
construct several different scenarios involving the same nodes but different
network devices and channels with different properties that you can easily
switch through. This would however probably only have sense in dynamically
generating scenarios like from a GUI or by some other means.
