Re: GNU in GSOC 2015 - Application sent

[Ludovic Courtès]

Hello,

Here are three ideas for Guix and dmd.  Others may follow.

Thanks,
Ludo’.


<h3 id="guix"><a href="/software/guix">GNU Guix</a></h3>

<p>GNU Guix is a purely functional package manager for the GNU system.
  The Guix System Distribution is GNU's advanced distribution.</p>

<h4 id="guix_hurd">Porting Guix to GNU/Hurd</h4>

<p>
  GNU Guix currently supports building packages for GNU/Linux only.  The
  goal of this project would be to allow it to cross-build and build
  packages for GNU/Hurd, and to provide a virtual machine image that
  boots into such a system.
</p>
<p>
  This would involve packaging Mach/Hurd/MiG/libc, adjusting allowing
  cross-compilation to GNU/Hurd, cross-compiling the “bootstrap
  binaries” for GNU/Hurd, and then working towards support for GNU/Hurd
  in the <code>(gnu system)</code> Guix modules.  This last point would
  allow a VM image of the complete system to be built.
</p>

<h4 id="guix_dhcp">Implementing a DHCP client in Guile Scheme</h4>

<p>
  The goal of this project is to write a DHCP client library in Guile
  Scheme.  The library will then be usable as a dmd service, thereby
  providing better integration.

<h3 id="dmd"><a href="/software/dmd">GNU dmd</a></h3>

<p>GNU dmd is the init system used by <a href="/software/guix">GuixSD</a>,
  GNU's advanced distribution.</p>

<h4 id="dmd_units">Syntax and semantics of systemd units in GNU&nbsp;dmd</h4>

<p>
  GNU dmd has a <a
  href="/software/dmd/manual/html_node/Services.html">Scheme interface
  to define services</a>, most importantly their dependencies and
  actions associated with them.  The goal of this project is twofold.
  The first part consists in matching the semantics of systemd's <a
  
href="http://www.freedesktop.org/software/systemd/man/systemd.service.html";><code>.service</code></a>
  unit files, more precisely a subset thereof (for instance, the
  DBus-related part may be omitted.)  As part of this work, dmd should
  be extended with <a
  href="https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt";>cgroup</a>
  support on systems that support it.  dmd should also be extended with
  a procedure to load a <code>.service</code> file and return a
  <code>&lt;service&gt;</code> object.
</p>
<p>
  The second part will consist in implementing other types of <a
  href="http://www.freedesktop.org/software/systemd/man/systemd.unit.html";>
  units</a>, in particular <code>.device</code>.
