juju login change

[roger peppe]

Hi,

Just a heads up to say that we're planning on changing the "juju login"
command on juju tip soon so that (by default) it logs into a controller
not a username. This is a backwardly incompatible change - to
get the old behaviour, there will be a new "-u" flag.

This has landed in a feature branch as https://github.com/juju/juju/pull/7092
and will be proposed in develop soon.

Any feedback welcome.

  cheers
    rog.
