Re: Notifying post-install tools about screens seen by the user - spec V2

So this is how I thin the "specification" could look like based on the discussion so far:

* a single config file in /etc/sysconfig/anaconda
* the file contains one section for every spoke screen present during the installation
* section naming is based on the spoke class name for every screen
* each section contains a "visited" key with value of either 0 or 1
* each section might contain one or more changed_<setting>=1 keys
* the keys are there only if the user actually changed something and always equal 1
- the idea is basically to simplify the change reporting code to only report changes,
  so that we don't need to keep (at least for now) a directory of all things that can be
  changed on a spoke but just trigger an action that adds the given "changed_<setting>"
  line when the user actually touches something

Example:

[DatetimeSpoke]
visited=1
changed_timezone=1
changed_ntp=1
changed_timedate=1

[KeyboardSpoke]
visited=0

etc.

Also as implementing the changed_* logic is a a bit more involved than just tracking spoke
visits I propose that the initial implementation has change tracking just for the timedate spoke,
with change tracking for other spokes being implemented incrementally based on pre & post install tool
requirements.

Looking forward to further feedback! :)
