We can probably do better with the aliases, but I really think what we
want is a wrapper script that enables readline, ansi, and 280 character
tweets. An update to oysttyer could remove the need for settings
changes for 280.
@IvanExpert removed the raspbian-update call in setup as part of the
jessie compatibility commit, and the script's gone away in A2SERVER as
well. Also removed the other upgrade-handling aliases and the thin
wrapper for raspi-config.
This is similar to what's already done in A2SERVER, but there's both
more and less of it. Fewer scripts run during the installation phase
(generally just setup), but there's a lot more tools and pieces that are
downloaded.
This is complicated somewhat by the single setup script making it hard
to work on just one piece at a time. We'll begin addressing that soon.
