[Librem-5-dev] queries with dev kit environment set up

Thanks Darota,

Yes, I am talking about the USB serial as described in the linked
page[1]. There is says that root can login. This is not the case with
my board.

I have not yet got to the reflashing step. I will likely get to that
tomorrow. The ssh login checks appear prior to that on the page and I
am assuming that there is a sequence to the instructions (also note
that DHCP appears to be set up on my board since the IP specified did
not work and the IP that it did have fits within my local network's
DHCP allocation range).

The ssh session does not complain about key mismatch when given -vvv
(ssh to localhost after logging in via USB serial conn).
