Some callers expect CalledProcessError.output to have the output, so
pass up the stdout + stderr output.
This means failed runcmd template commands will log to program.log and
lorax.log
Fix up 2to3 complaints. I've decided to do with wrapping list
comprehension inside list() to get the generators to run in several
places instead of list(map( or list(filter( which seem less readable to
me.
Previously if there was an error during a novirt installation that
didn't exit the process there was no way to detect it. This uses the new
--remotelog option for anaconda to monitor the logs for errors using the
same criteria as it does when monitoring a virt install. If there is an
error the anaconda process will be terminated and the logs will be
gathered up into ./anaconda/
Switch to using execWith* so that the command and its output can be
logged. To capture the output setup a logger named "program"
livemedia-creator captures all of this into program.log
The anaconda execWithRedirect and execWithCapture functions are too
useful not to include. They also allow you to log all the execuatable's
output to a logfile. Added them under executils.py module which uses
the pylorax and a new program logger.
