I have discussed this and upon closer inspection, we actually we do have
an API for console-conf to get the username of a managed device, but the
logic that console-conf should follow is a bit more convoluted because
eventually we may have devices that are managed (and thus should not
allow configuring through console-conf), but do not have any users. So
console-conf should not assume that a managed has users and that a
device that has users is managed.
The flow that console-conf should follow is this:
if $(snap managed) is true:
if $(snap /v2/users) is not nil:
for user in $(snap /v2/users):
if /home/$user/ exists:
display "ssh user@IP..." forever
# else fallback to saying there are not managed users
display "device managed without user @ IP"
else:
display console-conf setup screen
The first API request for determining if a device is managed can be done
with an HTTP GET request to the snapd /v2/system-info endpoint after a
device is seeded, looking at the result.managed key. This is the
equivalent of running on the command line `snap managed`.
The second API request for determining the username of managing users
can be done with an HTTP GET request to the snapd /v2/users endpoint,
looking at the result key which is a list of user objects. console-conf
should iterate over all of these users, starting with the user with the
lowest ID (note that the ID here is not a UID, it is an internal
tracking mechanism for snapd, essentially first-come first serve for
created users), checking if the user has a /home directory, and if the
user has a home directory then we presume that the user could login via
SSH. The username key is the name of the user that should be displayed
in "ssh <user>@IP".
@xnox does that all make sense?
