------------------------------+-------------------------------
 Right now, we have two logging systems installed by default in the Fedora
 Cloud image. While obviously rsyslog needs to continue to be an option, I
 don't think we should be shipping it by default. (After dhclient, it's the
 second-largest memory consumer, for one thing.) This requires some rework
 to the cloud-init package -- that's what's pulling it in now.

 We should also consider the journal options we want by default; probably
 settings optimized for less memory consumption are better.
