<h2> Related resources </h2>
<ul>
<li> <tt>s6-linux-utils</tt> is discussed on the
<a href="http://skarnet.org/lists.html#skaware">skaware</a> mailing-list. </li>
</ul>
<h2> Similar work </h2>
<p>
There are several good projects aiming to provide a minimal userspace
environment for Linux, suitable for embedded systems. Among them, for
instance:
</p>
<ul>
<li> <a href="http://busybox.net/">BusyBox</a> </li>
<li> <a href="http://landley.net/code/toybox/">toybox</a> </li>
</ul>
<p>
Most of the time, these projects aim to implement standard commands in a
lightweight way, and
they do it well enough. So, although some standard reimplentation already
exists in s6-linux-utils and its sibling package
<a href="http://skarnet.org/software/s6-portable-utils/">s6-portable-utils</a>,
it is an explicit non-goal of those packages to duplicate the work of those
projects, and no more rewriting of standard commands will occur.
