  14                 <description>&lt;p&gt;A few days ago I decided to try to help the Hurd people to get
  15 their changes into sysvinit, to allow them to use the normal sysvinit
  16 boot system instead of their old one.  This follow up on the
  17 &lt;a href=&quot;https://teythoon.cryptobitch.de//categories/gsoc.html&quot;&gt;great
  18 Google Summer of Code work&lt;/a&gt; done last summer by Justus Winter to
  19 get Debian on Hurd working more like Debian on Linux.  To get started,
  20 I downloaded a prebuilt hard disk image from
  21 &lt;a href=&quot;http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz&quot;&gt;http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz&lt;/a&gt;,
  22 and started it using virt-manager.&lt;/p&gt;
  23
  24 &lt;p&gt;The first think I had to do after logging in (root without any
  25 password) was to get the network operational.  I followed
  26 &lt;a href=&quot;https://www.debian.org/ports/hurd/hurd-install&quot;&gt;the
  27 instructions on the Debian GNU/Hurd ports page&lt;/a&gt; and ran these
  28 commands as root to get the machine to accept a IP address from the
  29 kvm internal DHCP server:&lt;/p&gt;
  30
  31 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
  32 settrans -fgap /dev/netdde /hurd/netdde
  33 kill $(ps -ef|awk &#39;/[p]finet/ { print $2}&#39;)
  34 kill $(ps -ef|awk &#39;/[d]evnode/ { print $2}&#39;)
  35 dhclient /dev/eth0
  36 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
  37
  38 &lt;p&gt;After this, the machine had internet connectivity, and I could
  39 upgrade it and install the sysvinit packages from experimental and
  40 enable it as the default boot system in Hurd.&lt;/p&gt;
  41
  42 &lt;p&gt;But before I did that, I set a password on the root user, as ssh is
  43 running on the machine it for ssh login to work a password need to be
  44 set.  Also, note that a bug somewhere in openssh on Hurd block
  45 compression from working.  Remember to turn that off on the client
  46 side.&lt;/p&gt;
  47
  48 &lt;p&gt;Run these commands as root to upgrade and test the new sysvinit
  49 stuff:&lt;/p&gt;
  50
  51 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
  52 cat &gt; /etc/apt/sources.list.d/experimental.list &amp;lt;&amp;lt;EOF
  53 deb http://http.debian.net/debian/ experimental main
  54 EOF
  55 apt-get update
  56 apt-get dist-upgrade
  57 apt-get install -t experimental initscripts sysv-rc sysvinit \
  58     sysvinit-core sysvinit-utils
  59 update-alternatives --config runsystem
  60 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
  61
  62 &lt;p&gt;To reboot after switching boot system, you have to use
  63 &lt;tt&gt;reboot-hurd&lt;/tt&gt; instead of just &lt;tt&gt;reboot&lt;/tt&gt;, as there is not
  64 yet a sysvinit process able to receive the signals from the normal
  65 &#39;reboot&#39; command.  After switching to sysvinit as the boot system,
  66 upgrading every package and rebooting, the network come up with DHCP
  67 after boot as it should, and the settrans/pkill hack mentioned at the
  68 start is no longer needed.  But for some strange reason, there are no
  69 longer any login prompt in the virtual console, so I logged in using
  70 ssh instead.
  71
  72 &lt;p&gt;Note that there are some race conditions in Hurd making the boot
  73 fail some times.  No idea what the cause is, but hope the Hurd porters
  74 figure it out.  At least Justus said on IRC (#debian-hurd on
  75 irc.debian.org) that they are aware of the problem.  A way to reduce
  76 the impact is to upgrade to the Hurd packages built by Justus by
  77 adding this repository to the machine:&lt;/p&gt;
  78
  79 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
  80 cat &gt; /etc/apt/sources.list.d/hurd-ci.list &amp;lt;&amp;lt;EOF
  81 deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
  82 EOF
  83 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
  84
  85 &lt;p&gt;At the moment the prebuilt virtual machine get some packages from
  86 http://ftp.debian-ports.org/debian, because some of the packages in
  87 unstable do not yet include the required patches that are lingering in
  88 BTS.  This is the completely list of &quot;unofficial&quot; packages installed:&lt;/p&gt;
  89
  90 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
  91 # aptitude search &#39;?narrow(?version(CURRENT),?origin(Debian Ports))&#39;
  92 i   emacs                   - GNU Emacs editor (metapackage)

 106 i A xserver-xorg-input-all  - X.Org X server -- input driver metapackage
 107 #
 108 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 109
 110 &lt;p&gt;All in all, testing hurd has been an interesting experience. :)
 111 X.org did not work out of the box and I never took the time to follow
 112 the porters instructions to fix it.  This time I was interested in the
 113 command line stuff.&lt;p&gt;
