+
+<p>While at Debconf11, I have several times during discussions
+mentioned the issues I believe should be improved in Debian for its
+desktop to be useful for more people. The use case for this is my
+parents, which are currently running Kubuntu which solve the
+issues.</p>
+
+<p>I suspect these four missing features are not very hard to
+implement. After all, they are present in Ubuntu, so if we wanted to
+do this in Debian we would have a source.</p>
+
+<ol>
+
+<li><strong>Simple GUI based upgrade of packages.</strong> When there
+are new packages available for upgrades, a icon in the KDE status bar
+indicate this, and clicking on it will activate the simple upgrade
+tool to handle it. I have no problem guiding both of my parents
+through the process over the phone. If a kernel reboot is required,
+this too is indicated by the status bars and the upgrade tool. Last
+time I checked, nothing with the same features was working in KDE in
+Debian.</li>
+
+<li><strong>Simple handling of missing Firefox browser
+plugins.</strong> When the browser encounter a MIME type it do not
+currently have a handler for, it will ask the user if the system
+should search for a package that would add support for this MIME type,
+and if the user say yes, the APT sources will be searched for packages
+advertising the MIME type in their control file (visible in the
+Packages file in the APT archive). If one or more packages are found,
+it is a simple click of the mouse to add support for the missing mime
+type. If the package require the user to accept some non-free
+license, this is explained to the user. The entire process make it
+more clear to the user why something do not work in the browser, and
+make the chances higher for the user to blame the web page authors and
+not the browser for any missing features.</li>
+
+<li><strong>Simple handling of missing multimedia codec/format
+handlers.</strong> When the media players encounter a format or codec
+it is not supporting, a dialog pop up asking the user if the system
+should search for a package that would add support for it. This
+happen with things like MP3, Windows Media or H.264. The selection
+and installation procedure is very similar to the Firefox browser
+plugin handling. This is as far as I know implemented using a
+gstreamer hook. The end result is that the user easily get access to
+the codecs that are present from the APT archives available, while
+explaining more on why a given format is unsupported by Ubuntu.</li>
+
+<li><strong>Better browser handling of some MIME types.</strong> When
+displaying a text/plain file in my Debian browser, it will propose to
+start emacs to show it. If I remember correctly, when doing the same
+in Kunbutu it show the file as a text file in the browser. At least I
+know Opera will show text files within the browser. I much prefer the
+latter behaviour.</li>
+
+</ol>
+
+<p>There are other nice features as well, like the simplified suite
+upgrader, but given that I am the one mostly doing the dist-upgrade,
+it do not matter much.</p>
+
+<p>I really hope we could get these features in place for the next
+Debian release. It would require the coordinated effort of several
+maintainers, but would make the end user experience a lot better.</p>

+ </div>
+ <div class="date">

+
+ <div class="body">
+
+<p>In the Debian boot system, several packages include scripts that
+are started from /etc/rcS.d/. In fact, there is a bite more of them
+than make sense, and this causes a few problems. What kind of
+problems, you might ask. There are at least two problems. The first
+is that it is not possible to recover a machine after switching to
+runlevel 1. One need to actually reboot to get the machine back to
+the expected state. The other is that single user boot will sometimes
+run into problems because some of the subsystems are activated before
+the root login is presented, causing problems when trying to recover a
+machine from a problem in that subsystem. A minor additional point is
+that moving more scripts out of rcS.d/ and into the other rc#.d/
+directories will increase the amount of scripts that can run in
+parallel during boot, and thus decrease the boot time.</p>
+
+<p>So, which scripts should start from rcS.d/. In short, only the
+scripts that _have_ to execute before the root login prompt is
+presented during a single user boot should go there. Everything else
+should go into the numeric runlevels. This means things like
+lm-sensors, fuse and x11-common should not run from rcS.d, but from
+the numeric runlevels. Today in Debian, there are around 115 init.d
+scripts that are started from rcS.d/, and most of them should be moved
+out. Do your package have one of them? Please help us make single
+user and runlevel 1 better by moving it.</p>
+
+<p>Scripts setting up the screen, keyboard, system partitions
+etc. should still be started from rcS.d/, but there is for example no
+need to have the network enabled before the single user login prompt
+is presented.</p>
+
+<p>As always, things are not so easy to fix as they sound. To keep
+Debian systems working while scripts migrate and during upgrades, the
+scripts need to be moved from rcS.d/ to rc2.d/ in reverse dependency
+order, ie the scripts that nothing in rcS.d/ depend on can be moved,
+and the next ones can only be moved when their dependencies have been
+moved first. This migration must be done sequentially while we ensure
+that the package system upgrade packages in the right order to keep
+the system state correct. This will require some coordination when it
+comes to network related packages, but most of the packages with
+scripts that should migrate do not have anything in rcS.d/ depending
+on them. Some packages have already been updated, like the sudo
+package, while others are still left to do. I wish I had time to work
+on this myself, but real live constrains make it unlikely that I will
+find time to push this forward.</p>
