ipv6 should be enabled on Raspbian nowadays, so we should no longer need
to modify the stock exim configuration. If it gives you an error on
startup, let me know and we'll put it back.
It turns out nc does a pretty decent ftp client and might be a good
alternative to cftp which … really never went anywhere and is awfully
easy to crash.
Another temporary script. This performs the tasks from ivan.sh related
to installCommTools. It differs from that block (which has not yet been
formally replaced) primarily by having a rewritten and hopefully more
logical installation for oysttyer.
Oysttyer probably should be broken into its own script—all of these
things should be really—but this one in particular because it's so
involved even compared to other installations because we have stuff we
need to clean up first.
