  32         <p>A few days ago I decided to try to help the Hurd people to get
  33 their changes into sysvinit, to allow them to use the normal sysvinit
  34 boot system instead of their old one.  This follow up on the
  35 <a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
  36 Google Summer of Code work</a> done last summer by Justus Winter to
  37 get Debian on Hurd working more like Debian on Linux.  To get started,
  38 I downloaded a prebuilt hard disk image from
  39 <a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
  40 and started it using virt-manager.</p>
  41
  42 <p>The first think I had to do after logging in (root without any
  43 password) was to get the network operational.  I followed
  44 <a href="https://www.debian.org/ports/hurd/hurd-install">the
  45 instructions on the Debian GNU/Hurd ports page</a> and ran these
  46 commands as root to get the machine to accept a IP address from the
  47 kvm internal DHCP server:</p>
  48
  49 <p><blockquote><pre>
  50 settrans -fgap /dev/netdde /hurd/netdde
  51 kill $(ps -ef|awk '/[p]finet/ { print $2}')
  52 kill $(ps -ef|awk '/[d]evnode/ { print $2}')
  53 dhclient /dev/eth0
  54 </pre></blockquote></p>
  55
  56 <p>After this, the machine had internet connectivity, and I could
  57 upgrade it and install the sysvinit packages from experimental and
  58 enable it as the default boot system in Hurd.</p>
  59
  60 <p>But before I did that, I set a password on the root user, as ssh is
  61 running on the machine it for ssh login to work a password need to be
  62 set.  Also, note that a bug somewhere in openssh on Hurd block
  63 compression from working.  Remember to turn that off on the client
  64 side.</p>
  65
  66 <p>Run these commands as root to upgrade and test the new sysvinit
  67 stuff:</p>
  68
  69 <p><blockquote><pre>
  70 cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
  71 deb http://http.debian.net/debian/ experimental main
  72 EOF
  73 apt-get update
  74 apt-get dist-upgrade
  75 apt-get install -t experimental initscripts sysv-rc sysvinit \
  76     sysvinit-core sysvinit-utils
  77 update-alternatives --config runsystem
  78 </pre></blockquote></p>
  79
  80 <p>To reboot after switching boot system, you have to use
  81 <tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
  82 yet a sysvinit process able to receive the signals from the normal
  83 'reboot' command.  After switching to sysvinit as the boot system,
  84 upgrading every package and rebooting, the network come up with DHCP
  85 after boot as it should, and the settrans/pkill hack mentioned at the
  86 start is no longer needed.  But for some strange reason, there are no
  87 longer any login prompt in the virtual console, so I logged in using
  88 ssh instead.
  89
  90 <p>Note that there are some race conditions in Hurd making the boot
  91 fail some times.  No idea what the cause is, but hope the Hurd porters
  92 figure it out.  At least Justus said on IRC (#debian-hurd on
  93 irc.debian.org) that they are aware of the problem.  A way to reduce
  94 the impact is to upgrade to the Hurd packages built by Justus by
  95 adding this repository to the machine:</p>
  96
  97 <p><blockquote><pre>
  98 cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
  99 deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
 100 EOF
 101 </pre></blockquote></p>
 102
 103 <p>At the moment the prebuilt virtual machine get some packages from
 104 http://ftp.debian-ports.org/debian, because some of the packages in
 105 unstable do not yet include the required patches that are lingering in
 106 BTS.  This is the completely list of "unofficial" packages installed:</p>
 107
 108 <p><blockquote><pre>
 109 # aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
 110 i   emacs                   - GNU Emacs editor (metapackage)

 127
 128 <p>All in all, testing hurd has been an interesting experience. :)
 129 X.org did not work out of the box and I never took the time to follow
 130 the porters instructions to fix it.  This time I was interested in the
 131 command line stuff.<p>
