+ <p>Five years ago,
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html">I
+measured what the most supported MIME type in Debian was</a>, by
+analysing the desktop files in all packages in the archive. Since
+then, the DEP-11 AppStream system has been put into production, making
+the task a lot easier. This made me want to repeat the measurement,
+to see how much things changed. Here are the new numbers, for
+unstable only this time:
+
+<p><strong>Debian Unstable:</strong></p>
+
+<pre>
+ count MIME type
+ ----- -----------------------
+ 56 image/jpeg
+ 55 image/png
+ 49 image/tiff
+ 48 image/gif
+ 39 image/bmp
+ 38 text/plain
+ 37 audio/mpeg
+ 34 application/ogg
+ 33 audio/x-flac
+ 32 audio/x-mp3
+ 30 audio/x-wav
+ 30 audio/x-vorbis+ogg
+ 29 image/x-portable-pixmap
+ 27 inode/directory
+ 27 image/x-portable-bitmap
+ 27 audio/x-mpeg
+ 26 application/x-ogg
+ 25 audio/x-mpegurl
+ 25 audio/ogg
+ 24 text/html
+</pre>
+
+<p>The list was created like this using a sid chroot: "cat
+/var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz| zcat | awk '/^
+- \S+\/\S+$/ {print $2 }' | sort | uniq -c | sort -nr | head -20"</p>
+
+<p>It is interesting to see how image formats have passed text/plain
+as the most announced supported MIME type. These days, thanks to the
+AppStream system, if you run into a file format you do not know, and
+want to figure out which packages support the format, you can find the
+MIME type of the file using "file --mime <filename>", and then
+look up all packages announcing support for this format in their
+AppStream metadata (XML or .desktop file) using "appstreamcli
+what-provides mimetype <mime-type>. For example if you, like
+me, want to know which packages support inode/directory, you can get a
+list like this:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
+Package: anjuta
+Package: audacious
+Package: baobab
+Package: cervisia
+Package: chirp
+Package: dolphin
+Package: doublecmd-common
+Package: easytag
+Package: enlightenment
+Package: ephoto
+Package: filelight
+Package: gwenview
+Package: k4dirstat
+Package: kaffeine
+Package: kdesvn

+Package: nemo
+Package: pcmanfm
+Package: pcmanfm-qt
+Package: qweborf
+Package: ranger
+Package: sirikali
+Package: spacefm
+Package: spacefm
+Package: vifm
+%
+</pre></blockquote></p>
+
+<p>Using the same method, I can quickly discover that the Sketchup file
+format is not yet supported by any package in Debian:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype application/vnd.sketchup.skp
+Could not find component providing 'mimetype::application/vnd.sketchup.skp'.
+%
+</pre></blockquote></p>
+
+<p>Yesterday I used it to figure out which packages support the STL 3D
+format:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype application/sla|grep Package
+Package: cura
+Package: meshlab
+Package: printrun
+%
+</pre></blockquote></p>
+
+<p>PS: A new version of Cura was uploaded to Debian yesterday.</p>

+ <p>I received a very nice Christmas present today. As my regular
+readers probably know, I have been working on the
+<a href="http://packages.qa.debian.org/isenkram">the Isenkram
+system</a> for many years. The goal of the Isenkram system is to make
+it easier for users to figure out what to install to get a given piece
+of hardware to work in Debian, and a key part of this system is a way
+to map hardware to packages. Isenkram have its own mapping database,
+and also uses data provided by each package using the AppStream
+metadata format. And today,
+<a href="https://tracker.debian.org/pkg/appstream">AppStream</a> in
+Debian learned to look up hardware the same way Isenkram is doing it,
+ie using fnmatch():</p>
+

+
+<p>A similar query can be done using the combined AppStream and
+Isenkram databases using the isenkram-lookup tool:</p>
+
+<p><pre>

+
+<p>You can find modalias values relevant for your machine using
+<tt>cat $(find /sys/devices/ -name modalias)</tt>.
+
+<p>If you want to make this system a success and help Debian users
+make the most of the hardware they have, please
+help<a href="https://wiki.debian.org/AppStream/Guidelines">add
+AppStream metadata for your package following the guidelines</a>
+documented in the wiki. So far only 11 packages provide such
+information, among the several hundred hardware specific packages in
+Debian. The Isenkram database on the other hand contain 101 packages,
+mostly related to USB dongles. Most of the packages with hardware
+mapping in AppStream are LEGO Mindstorms related, because I have, as
+part of my involvement in
+<a href="https://wiki.debian.org/LegoDesigners">the Debian LEGO
+team</a> given priority to making sure LEGO users get proposed the
+complete set of packages in Debian for that particular hardware. The
+team also got a nice Christmas present today. The
+<a href="https://tracker.debian.org/pkg/nxt-firmware">nxt-firmware
+package</a> made it into Debian. With this package in place, it is
+now possible to use the LEGO Mindstorms NXT unit with only free
+software, as the nxt-firmware package contain the source and firmware
+binaries for the NXT brick.</p>

+ <p><a href="http://packages.qa.debian.org/isenkram">The Isenkram
+system</a> I wrote two years ago to make it easier in Debian to find
+and install packages to get your hardware dongles to work, is still
+going strong. It is a system to look up the hardware present on or
+connected to the current system, and map the hardware to Debian
+packages. It can either be done using the tools in isenkram-cli or
+using the user space daemon in the isenkram package. The latter will
+notify you, when inserting new hardware, about what packages to
+install to get the dongle working. It will even provide a button to
+click on to ask packagekit to install the packages.</p>
+
+<p>Here is an command line example from my Thinkpad laptop:</p>
+
+<p><pre>
+% isenkram-lookup
+bluez
+cheese
+ethtool
+fprintd
+fprintd-demo
+gkrellm-thinkbat

+pidgin-blinklight
+thinkfan
+tlp
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%
+</pre></p>
+
+<p>It can also list the firware package providing firmware requested
+by the load kernel modules, which in my case is an empty list because
+I have all the firmware my machine need:
+
+<p><pre>
+% /usr/sbin/isenkram-autoinstall-firmware -l
+info: did not find any firmware files requested by loaded kernel modules. exiting
+%
+</pre></p>
+
+<p>The last few days I had a look at several of the around 250
+packages in Debian with udev rules. These seem like good candidates
+to install when a given hardware dongle is inserted, and I found
+several that should be proposed by isenkram. I have not had time to
+check all of them, but am happy to report that now there are 97
+packages packages mapped to hardware by Isenkram. 11 of these
+packages provide hardware mapping using AppStream, while the rest are
+listed in the modaliases file provided in isenkram.</p>
+
+<p>These are the packages with hardware mappings at the moment. The

+
+<p>If you know of other packages, please let me know with a wishlist

+maintainer to
+<a href="https://wiki.debian.org/AppStream/Guidelines">add AppStream
+metadata according to the guidelines</a> to provide the information
+for everyone. In time, I hope to get rid of the isenkram specific

+
+<p>Note, the AppStream metadata for broadcom-sta-dkms is matching too
+much hardware, and suggest that the package with with any ethernet
+card. See <a href="http://bugs.debian.org/838735">bug #838735</a> for

+ <div class="body">
+ <p><a href="http://packages.qa.debian.org/isenkram">The Isenkram
+system</a> provide a practical and easy way to figure out which
+packages support the hardware in a given machine. The command line
+tool <tt>isenkram-lookup</tt> and the tasksel options provide a
+convenient way to list and install packages relevant for the current
+hardware during system installation, both user space packages and
+firmware packages. The GUI background daemon on the other hand provide
+a pop-up proposing to install packages when a new dongle is inserted
+while using the computer. For example, if you plug in a smart card
+reader, the system will ask if you want to install <tt>pcscd</tt> if
+that package isn't already installed, and if you plug in a USB video
+camera the system will ask if you want to install <tt>cheese</tt> if
+cheese is currently missing. This already work just fine.</p>
+
+<p>But Isenkram depend on a database mapping from hardware IDs to
+package names. When I started no such database existed in Debian, so
+I made my own data set and included it with the isenkram package and
+made isenkram fetch the latest version of this database from git using
+http. This way the isenkram users would get updated package proposals
+as soon as I learned more about hardware related packages.</p>
+
+<p>The hardware is identified using modalias strings. The modalias
+design is from the Linux kernel where most hardware descriptors are
+made available as a strings that can be matched using filename style
+globbing. It handle USB, PCI, DMI and a lot of other hardware related
+identifiers.</p>
+
+<p>The downside to the Isenkram specific database is that there is no
+information about relevant distribution / Debian version, making
+isenkram propose obsolete packages too. But along came AppStream, a
+cross distribution mechanism to store and collect metadata about
+software packages. When I heard about the proposal, I contacted the
+people involved and suggested to add a hardware matching rule using
+modalias strings in the specification, to be able to use AppStream for
+mapping hardware to packages. This idea was accepted and AppStream is
+now a great way for a package to announce the hardware it support in a
+distribution neutral way. I wrote
+<a href="http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html">a
+recipe on how to add such meta-information</a> in a blog post last
+December. If you have a hardware related package in Debian, please
+announce the relevant hardware IDs using AppStream.</p>
+
+<p>In Debian, almost all packages that can talk to a LEGO Mindestorms
+RCX or NXT unit, announce this support using AppStream. The effect is
+that when you insert such LEGO robot controller into your Debian
+machine, Isenkram will propose to install the packages needed to get
+it working. The intention is that this should allow the local user to
+start programming his robot controller right away without having to
+guess what packages to use or which permissions to fix.</p>
+
+<p>But when I sat down with my son the other day to program our NXT
+unit using his Debian Stretch computer, I discovered something
+annoying. The local console user (ie my son) did not get access to
+the USB device for programming the unit. This used to work, but no
+longer in Jessie and Stretch. After some investigation and asking
+around on #debian-devel, I discovered that this was because udev had
+changed the mechanism used to grant access to local devices. The
+ConsoleKit mechanism from <tt>/lib/udev/rules.d/70-udev-acl.rules</tt>
+no longer applied, because LDAP users no longer was added to the
+plugdev group during login. Michael Biebl told me that this method
+was obsolete and the new method used ACLs instead. This was good
+news, as the plugdev mechanism is a mess when using a remote user
+directory like LDAP. Using ACLs would make sure a user lost device
+access when she logged out, even if the user left behind a background
+process which would retain the plugdev membership with the ConsoleKit
+setup. Armed with this knowledge I moved on to fix the access problem
+for the LEGO Mindstorms related packages.</p>
+
+<p>The new system uses a udev tag, 'uaccess'. It can either be
+applied directly for a device, or is applied in
+/lib/udev/rules.d/70-uaccess.rules for classes of devices. As the
+LEGO Mindstorms udev rules did not have a class, I decided to add the
+tag directly in the udev rules files included in the packages. Here
+is one example. For the nqc C compiler for the RCX, the
+<tt>/lib/udev/rules.d/60-nqc.rules</tt> file now look like this:
+
+<p><pre>
+SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0694", ATTR{idProduct}=="0001", \
+ SYMLINK+="rcx-%k", TAG+="uaccess"
+</pre></p>
+
+<p>The key part is the 'TAG+="uaccess"' at the end. I suspect all
+packages using plugdev in their /lib/udev/rules.d/ files should be
+changed to use this tag (either directly or indirectly via
+<tt>70-uaccess.rules</tt>). Perhaps a lintian check should be created
+to detect this?</p>
+
+<p>I've been unable to find good documentation on the uaccess feature.
+It is unclear to me if the uaccess tag is an internal implementation
+detail like the udev-acl tag used by
+<tt>/lib/udev/rules.d/70-udev-acl.rules</tt>. If it is, I guess the
+indirect method is the preferred way. Michael
+<a href="https://github.com/systemd/systemd/issues/4288">asked for more
+documentation from the systemd project</a> and I hope it will make
+this clearer. For now I use the generic classes when they exist and
+is already handled by <tt>70-uaccess.rules</tt>, and add the tag
+directly if no such class exist.</p>

+ <p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
+system</a> is a user-focused solution in Debian for handling hardware
+related packages. The idea is to have a database of mappings between
+hardware and packages, and pop up a dialog suggesting for the user to
+install the packages to use a given hardware dongle. Some use cases
+are when you insert a Yubikey, it proposes to install the software
+needed to control it; when you insert a braille reader list it
+proposes to install the packages needed to send text to the reader;
+and when you insert a ColorHug screen calibrator it suggests to
+install the driver for it. The system work well, and even have a few
+command line tools to install firmware packages and packages for the
+hardware already in the machine (as opposed to hotpluggable hardware).</p>
+
+<p>The system was initially written using aptdaemon, because I found
+good documentation and example code on how to use it. But aptdaemon
+is going away and is generally being replaced by
+<a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
+so Isenkram needed a rewrite. And today, thanks to the great patch
+from my college Sunil Mohan Adapa in the FreedomBox project, the
+rewrite finally took place. I've just uploaded a new version of
+Isenkram into Debian Unstable with the patch included, and the default
+for the background daemon is now to use PackageKit. To check it out,
+install the <tt>isenkram</tt> package and insert some hardware dongle
+and see if it is recognised.</p>
+
+<p>If you want to know what kind of packages isenkram would propose for
+the machine it is running on, you can check out the isenkram-lookup
+program. This is what it look like on a Thinkpad X230:</p>
+
+<p><blockquote><pre>
+% isenkram-lookup
+bluez
+cheese
+fprintd
+fprintd-demo
+gkrellm-thinkbat
+hdapsd
+libpam-fprintd
+pidgin-blinklight
+thinkfan
+tleds
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%p
+</pre></blockquote></p>
+
+<p>The hardware mappings come from several places. The preferred way
+is for packages to announce their hardware support using
+<a href="https://www.freedesktop.org/software/appstream/docs/">the
+cross distribution appstream system</a>.
+See
+<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous

+ <p>Around three years ago, I created
+<a href="http://packages.qa.debian.org/isenkram">the isenkram
+system</a> to get a more practical solution in Debian for handing
+hardware related packages. A GUI system in the isenkram package will
+present a pop-up dialog when some hardware dongle supported by
+relevant packages in Debian is inserted into the machine. The same
+lookup mechanism to detect packages is available as command line
+tools in the isenkram-cli package. In addition to mapping hardware,

+install needed firmware packages automatically. The key for this
+system to work is a good way to map hardware to packages, in other
+words, allow packages to announce what hardware they will work
+with.</p>
+
+<p>I started by providing data files in the isenkram source, and
+adding code to download the latest version of these data files at run
+time, to ensure every user had the most up to date mapping available.
+I also added support for storing the mapping in the Packages file in
+the apt repositories, but did not push this approach because while I
+was trying to figure out how to best store hardware/package mappings,
+<a href="http://www.freedesktop.org/software/appstream/docs/">the
+appstream system</a> was announced. I got in touch and suggested to
+add the hardware mapping into that data set to be able to use
+appstream as a data source, and this was accepted at least for the
+Debian version of appstream.</p>
+
+<p>A few days ago using appstream in Debian for this became possible,
+and today I uploaded a new version 0.20 of isenkram adding support for
+appstream as a data source for mapping hardware to packages. The only
+package so far using appstream to announce its hardware support is my
+pymissile package. I got help from Matthias Klumpp with figuring out
+how do add the required
+<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata
+in pymissile</a>. I added a file debian/pymissile.metainfo.xml with
+this content:</p>
+
+<blockquote><pre>
+<?xml version="1.0" encoding="UTF-8"?>
+<component>
+ <id>pymissile</id>
+ <metadata_license>MIT</metadata_license>
+ <name>pymissile</name>
+ <summary>Control original Striker USB Missile Launcher</summary>
+ <description>
+ <p>
+ Pymissile provides a curses interface to control an original
+ Marks and Spencer / Striker USB Missile Launcher, as well as a
+ motion control script to allow a webcamera to control the
+ launcher.
+ </p>
+ </description>
+ <provides>
+ <modalias>usb:v1130p0202d*</modalias>
+ </provides>
+</component>
+</pre></blockquote>
+
+<p>The key for isenkram is the component/provides/modalias value,
+which is a glob style match rule for hardware specific strings
+(modalias strings) provided by the Linux kernel. In this case, it
+will map to all USB devices with vendor code 1130 and product code
+0202.</p>
+
+<p>Note, it is important that the license of all the metadata files
+are compatible to have permissions to aggregate them into archive wide
+appstream files. Matthias suggested to use MIT or BSD licenses for
+these files. A challenge is figuring out a good id for the data, as
+it is supposed to be globally unique and shared across distributions
+(in other words, best to coordinate with upstream what to use). But
+it can be changed later or, so we went with the package name as
+upstream for this project is dormant.</p>
+
+<p>To get the metadata file installed in the correct location for the
+mirror update scripts to pick it up and include its content the
+appstream data source, the file must be installed in the binary
+package under /usr/share/appdata/. I did this by adding the following
+line to debian/pymissile.install:</p>
+
+<blockquote><pre>
+debian/pymissile.metainfo.xml usr/share/appdata
+</pre></blockquote>
+
+<p>With that in place, the command line tool isenkram-lookup will list
+all packages useful on the current computer automatically, and the GUI
+pop-up handler will propose to install the package not already
+installed if a hardware dongle is inserted into the machine in
+question.</p>
+
+<p>Details of the modalias field in appstream is available from the
+<a href="https://wiki.debian.org/DEP-11">DEP-11</a> proposal.</p>
+
+<p>To locate the modalias values of all hardware present in a machine,
+try running this command on the command line:</p>
+
+<blockquote><pre>
+cat $(find /sys/devices/|grep modalias)
+</pre></blockquote>
