Bah.
1. It might make a lot more sense to use the installer's existing
syslogging support instead of writing our own log. (As a side benefit,
syslogs are timestamped.) You can use what appears to be a reasonably
standard logger(1) to send messages. They end up in /var/log/syslog.
2. I'm skeptical that your netcat MTA works. The client not waiting for
server responses is one of the biggest giveaways that a message is spam
before it's even read; I suspect this will be highly unreliable. The
installer has a built-in httpd for getting debug logs off -- you can just
run "httpd", which will spawn a daemon serving /var/log over port 80, or
you can do something involving `udpkg --configure --force-configure
save-logs`, which also symlinks a few useful things into /var/log. (The
latter is what the installer main menu's "Save debug logs" option runs.
3. If networking doesn't work, how is sending mail supposed to work?
