            emulate right/middle click using keyboard keys. Edit
            \texttt{/etc/defaults/mouseemu} to configure.

            I will update the slides.

\begin{frame}{yaboot}
    Debian installs yaboot, a bootloader that works on OpenFirmware. Out of the
    box, it works fine. But you may wish to tweak it.

    \begin{itemize}[<+->]
        \item Configured in \texttt{/etc/yaboot.conf}
        \item Adjust \texttt{timeout=} to your liking (potentially \texttt{0})
        \item Add any kernel flags you need with \texttt{append=}
        \item Run \texttt{ybin} as root to regenerate the bootloader and bless
            it with Holy Penguin Pee
