  24       <div class="date">25th November 2016</div>
  25       <div class="body"><p>Two years ago, I did some experiments with eatmydata and the Debian
  26 installation system, observing how using
  27 <a href="http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html">eatmydata
  28 could speed up the installation</a> quite a bit.  My testing measured
  29 speedup around 20-40 percent for Debian Edu, where we install around
  30 1000 packages from within the installer.  The eatmydata package
  31 provide a way to disable/delay file system flushing.  This is a bit
  32 risky in the general case, as files that should be stored on disk will
  33 stay only in memory a bit longer than expected, causing problems if a
  34 machine crashes at an inconvenient time.  But for an installation, if
  35 the machine crashes during installation the process is normally
  36 restarted, and avoiding disk operations as much as possible to speed
  37 up the process make perfect sense.
  38
  39 <p>I added code in the Debian Edu specific installation code to enable
  40 <a href="https://tracker.debian.org/pkg/libeatmydata">eatmydata</a>,
  41 but did not have time to push it any further.  But a few months ago I
  42 picked it up again and worked with the libeatmydata package maintainer
  43 Mattia Rizzolo to make it easier for everyone to get this installation
  44 speedup in Debian.  Thanks to our cooperation There is now an
  45 eatmydata-udeb package in Debian testing and unstable, and simply
  46 enabling/installing it in debian-installer (d-i) is enough to get the
  47 quicker installations.  It can be enabled using preseeding.  The
  48 following untested kernel argument should do the trick:</p>
  49
  50 <blockquote><pre>
  51 preseed/early_command="anna-install eatmydata-udeb"
  52 </pre></blockquote>
  53
  54 <p>This should ask d-i to install the package inside the d-i
  55 environment early in the installation sequence.  Having it installed
  56 in d-i in turn will make sure the relevant scripts are called just
  57 after debootstrap filled /target/ with the freshly installed Debian
  58 system to configure apt to run dpkg with eatmydata.  This is enough to
  59 speed up the installation process.  There is a proposal to
  60 <a href="https://bugs.debian.org/841153">extend the idea a bit further
  61 by using /etc/ld.so.preload instead of apt.conf</a>, but I have not
  62 tested its impact.</p>
