Since we started using type_very_safely for typing the root
password, we starting hitting a race issue. If we complete the
root password spoke so slowly that the software deployment
process completes in the meantime, anaconda will wait until we
complete the spoke then immediately flip to the 'post-install
configuration' step, at which point access to the USER CREATION
spoke is blocked.
We don't hit this case on regular RPM installs or live installs
as the deployment phase still takes a while for both of those,
but we are sometimes hitting it for the Atomic ostree install
image, as the software deployment phase is pretty fast there.
We *could* just not bother creating a user and testing we can
log in as a user for that test, but I don't like that approach,
we *should* be testing that user creation and login works OK
for ostree installs. So instead, let's just type the root
password a bit less safely for ostree installs; this will be
more vulnerable to typing errors but hopefully will avoid the
race problem.
