Root console in anaconda got broken by RHBZ #1222413 - no
shell on tty2. Decided to clean up console use in general as
part of fixing it.
This creates a class 'fedorabase' and has 'anacondalog' and
'fedoralog' both inherit from it. boot_to_login_screen is
moved there (as it seems appropriate) and it has a new
method, console_login, which basically handles 'get me a
shell on a console': if we're already at one it returns,
if not it'll type the user name and the password *if
necessary* (sometimes it's not) and return once it sees a
prompt. It takes a hash of named parameters for user,
password and 'check', which is whether it should die if it
fails to reach a console or not (some users don't want it
to).
anacondalog and fedoralog both get 'root_console' methods
which do something appropriate and then call
console_login; both have a hash of named parameters,
anacondalog's version only bothers with 'check', while
fedoralog's also accepts 'tty' to pick the tty to use.
This also adjusts all things which try to get to a console
prompt to use either root_console or console_login as
appropriate.
It also tweaks the needle tags a bit, drops some unneeded
needles, and adds a new 'user console prompt' needle; we
really just need two versions of the root prompt needle
and two of the user prompt needle (one for <F23, one for
F23+ - the console font changed in F23, and the @ character
at least doesn't match between the two). I think we still
need the <F23 case for upgrade tests, for now.
So I should note - I really don't quite get why the original code is set to log in as user then 'su' to root, if both user and root accounts are configured. I don't know if the intent was to test that 'su' works, or what.
We can twiddle this quite easily. If we want to test su for some reason we can actually just run 'su' then call console_login, because console_login actually ought to handle the 'su' password prompt successfully. But for now I just made it so when both user and root accounts are configured it ought to log in as user, then log out (thanks to the $bad check in console_login) and log in again as root, which I guess proves that logging in as both user and root works.
