HEADLINE: Switch to persistent journald by default
DESCRIPTION: Right now, Debian's default install includes rsyslog, and every message gets logged twice. Once in rsyslog on disk, and once in journald in memory. Let's turn on the persistent journal by default, and demote rsyslog to optional. (People who want syslog-based logging can still trivially install it, such as people in an environment that wants network-based syslogging. But that's not the common case.) This will make it easier to get urgent messages displayed in desktop environments as well.
