+Title: Testing sysvinit from experimental in Debian Hurd
+Tags: english, debian, bootsystem
+Date: 2014-02-03 13:40
+
+<p>A few days ago I decided to try to help the Hurd people to get
+their changes into sysvinit, to allow them to use the normal sysvinit
+boot system instead of their old one.  This follow up on the
+<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
+Google Summer of Code work</a> done last summer by Justus Winter to
+get Debian on Hurd working more like Debian on Linux.  To get started,
+I downloaded a prebuilt hard disk image from
+<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>,
+and started it using virt-manager.</p>
+
+<p>The first think I had to do after logging in (root without any
+password) was to get the network operational.  I followed
+<a href="https://www.debian.org/ports/hurd/hurd-install">the
+instructions on the Debian GNU/Hurd ports page</a> and ran these
+commands as root to get the machine to accept a IP address from the
+kvm internal DHCP server:</p>
+
+<p><blockquote><pre>
+settrans -fgap /dev/netdde /hurd/netdde 
+pkill pfinet
+pkill devnode
+dhclient -v /dev/eth0
+</pre></blockquote></p>
+
+<p>After this, the machine had internet connectivity, and I could
+upgrade it and install the sysvinit packages from experimental and
+enable it as the default boot system in Hurd.</p>
+
+<p>But before I did that, I set a password on the root user, as ssh is
+running on the machine it for ssh login to work a password need to be
+set.  Also, note that a bug somewhere in openssh on Hurd block
+compression from working.  Remember to turn that off on the client
+side.</p>
+
+<p>Run these commands as root to upgrade and test the new sysvinit
+stuff:</p>
+
+<p><blockquote><pre>
+cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
+deb http://http.debian.net/debian/ experimental main
+EOF
+apt-get update
+apt-get dist-upgrade
+apt-get install -t experimental initscripts sysv-rc sysvinit \
+    sysvinit-core sysvinit-utils 
+update-alternatives --config runsystem
+</pre></blockquote></p>
+
+<p>To reboot after switching boot system, you have to use
+<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
+yet a sysvinit process able to receive the signals from the normal
+'reboot' command.  After switching to sysvinit as the boot system,
+upgrading every package and rebooting, the network come up with DHCP
+after boot as it should, and the settrans/pkill hack mentioned at the
+start is no longer needed.  But for some strange reason, there are no
+longer any login prompt in the virtual console, so I logged in using
+ssh instead.
+
+<p>Note that there are some race conditions in Hurd making the boot
+fail some times.  No idea what the cause is, but hope the Hurd porters
+figure it out.  At least Justus said on IRC (#debian-hurd on
+irc.debian.org) that they are aware of the problem.  A way to reduce
+the impact is to upgrade to the Hurd packages built by Justus by
+adding this repository to the machine:</p>
+
+<p><blockquote><pre>
+cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
+deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
+EOF
+</pre></blockquote></p>
+
+<p>At the moment the prebuilt virtual machine get some packages from
+http://ftp.debian-ports.org/debian, because some of the packages in
+unstable do not yet include the required patches that are lingering in
+BTS.  This is the completely list of "unofficial" packages installed:</p>
+
+<p><blockquote><pre>
+# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
+i   emacs                   - GNU Emacs editor (metapackage)
+i   gdb                     - GNU Debugger

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