\section{Introduction}
\begin{frame}{What is an init system?}
An init system is the first process (PID 1) started in a Unix like system. It handles:
\begin{itemize}
\item Starting system processes and services to prepare environment
\item Adopting and ``reaping'' orphaned processes
\end{itemize}
\end{frame}
\begin{frame}{Classical init systems}
Init systems before systemd - such as SysVinit - were very simple.
\begin{itemize}
\item Services and processes to run are organised into ``init scripts''
\item Scripts are linked to specific runlevels
\item Init system is configured to boot into a runlevel
\end{itemize}
\end{frame}
\section{systemd}
\begin{frame}{Can we do better?}
\begin{itemize}
\item ``legacy'' init systems have a lot of drawbacks
\item Apple is taking a different approach on OS X
\item Systemd project was founded to address these issues
\end{itemize}
\end{frame}
\begin{frame}{Systemd design goals}
\begin{itemize}
\item Expressing service dependencies
\item Monitoring service status
\item Enable parallel service startups
\item Ease of use
\end{itemize}
