'service aria2 stop' etc does not work. Probably not a problem, except when I'm trying to figure out why setuid/setgid doesn't want to work in upstart.

I've tried swapping the paths to a local user (/home/aria2/... instead of /etc/aria2/...) and adding setuid aria2, setgid aria2 to aria2.conf, but the logfile shows that it's already been bound, then the process crashes repeatedly. Any ideas here? I haven't been able to make this work at all, but I know it's possible (I did get calibre to run under another user, but that's in /etc/init.d, not upstart, which I'd prefer)

You might also consider (so you don't need to edit the file afterwards...)

read -e -i "aria2" -p "Username? " ariauser
read -e -i "aria2" -p "Password? " ariapass
echo rpc-user=$ariauser >> /etc/aria2/aria2.conf
echo rpc-passwd=$ariapass >> /etc/aria2/aria2.conf
