(cherry picked from commit da8326fd58)
The ppc config files were missing from the live config_files directory
and ppc needs the correct lib directory so lmc has been switched to use
ArchData driven from the installed kernel arch.
Resolves: rhbz#1102318
(cherry picked from commit 59f256e989)
Make kernel args the same in every config.
Put 'quiet' at the end of the line - it's usually the first thing a user removes when debugging.
Fill missing product versions in.
Distinguish between 'install' (installation media) and 'start' (live media).
live media isn't exactly the same as the Anaconda install media. Right
now this amounts to needing a root= cmdline argument but in the future
there may be other differences.
This also reverts 5437557846 on the new copies of the templates.
