this one looks ok.

this one will require a second rootfs partition to allow you installing 
updates when running from the productive one.

There seems to be a communication issue between the command line client 
and the service. Did you try to start the service. Do you have the d-bus 
config installed? Could you get any log data from the service itself?

This looks ok so far.

I assume you executed this on the target?
Obviously, there is a certificate verification error. Did you set up the 
key, cert and keychain correctly? If you want to (for test-purpose) 
inspect the bundle without verification, you can use the `--no-verify` 
argument. But for installation the verification is mandatory thus it 
should work with `info`, too.

In the documentation there is the chapter `Interfacing with the bootloader`:

http://rauc.readthedocs.io/en/latest/integration.html#interfacing-with-the-bootloader

Did you already try what is described in there? If there is some 
information missing please let us know. The subsection "U-Boot" also 
points you to the u-boot example script located in the `contrib/` 
folder. This should be a good starting point.


Best regards

Enrico
