  32         <p><a href="http://packages.qa.debian.org/isenkram">The Isenkram
  33 system</a> provide a practical and easy way to figure out which
  34 packages support the hardware in a given machine.  The command line
  35 tool <tt>isenkram-lookup</tt> and the tasksel options provide a
  36 convenient way to list and install packages relevant for the current
  37 hardware during system installation, both user space packages and
  38 firmware packages. The GUI background daemon on the other hand provide
  39 a pop-up proposing to install packages when a new dongle is inserted
  40 while using the computer.  For example, if you plug in a smart card
  41 reader, the system will ask if you want to install <tt>pcscd</tt> if
  42 that package isn't already installed, and if you plug in a USB video
  43 camera the system will ask if you want to install <tt>cheese</tt> if
  44 cheese is currently missing.  This already work just fine.</p>
  45
  46 <p>But Isenkram depend on a database mapping from hardware IDs to
  47 package names.  When I started no such database existed in Debian, so
  48 I made my own data set and included it with the isenkram package and
  49 made isenkram fetch the latest version of this database from git using
  50 http.  This way the isenkram users would get updated package proposals
  51 as soon as I learned more about hardware related packages.</p>
  52
  53 <p>The hardware is identified using modalias strings.  The modalias
  54 design is from the Linux kernel where most hardware descriptors are
  55 made available as a strings that can be matched using filename style
  56 globbing.  It handle USB, PCI, DMI and a lot of other hardware related
  57 identifiers.</p>
  58
  59 <p>The downside to the Isenkram specific database is that there is no
  60 information about relevant distribution / Debian version, making
  61 isenkram propose obsolete packages too.  But along came AppStream, a
  62 cross distribution mechanism to store and collect metadata about
  63 software packages.  When I heard about the proposal, I contacted the
  64 people involved and suggested to add a hardware matching rule using
  65 modalias strings in the specification, to be able to use AppStream for
  66 mapping hardware to packages.  This idea was accepted and AppStream is
  67 now a great way for a package to announce the hardware it support in a
  68 distribution neutral way.  I wrote
  69 <a href="http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html">a
  70 recipe on how to add such meta-information</a> in a blog post last
  71 December.  If you have a hardware related package in Debian, please
  72 announce the relevant hardware IDs using AppStream.</p>
  73
  74 <p>In Debian, almost all packages that can talk to a LEGO Mindestorms
  75 RCX or NXT unit, announce this support using AppStream.  The effect is
  76 that when you insert such LEGO robot controller into your Debian
  77 machine, Isenkram will propose to install the packages needed to get
  78 it working.  The intention is that this should allow the local user to
  79 start programming his robot controller right away without having to
  80 guess what packages to use or which permissions to fix.</p>
  81
  82 <p>But when I sat down with my son the other day to program our NXT
  83 unit using his Debian Stretch computer, I discovered something
  84 annoying.  The local console user (ie my son) did not get access to
  85 the USB device for programming the unit.  This used to work, but no
  86 longer in Jessie and Stretch.  After some investigation and asking
  87 around on #debian-devel, I discovered that this was because udev had
  88 changed the mechanism used to grant access to local devices.  The
  89 ConsoleKit mechanism from <tt>/lib/udev/rules.d/70-udev-acl.rules</tt>
  90 no longer applied, because LDAP users no longer was added to the
  91 plugdev group during login.  Michael Biebl told me that this method
  92 was obsolete and the new method used ACLs instead.  This was good
  93 news, as the plugdev mechanism is a mess when using a remote user
  94 directory like LDAP.  Using ACLs would make sure a user lost device
  95 access when she logged out, even if the user left behind a background
  96 process which would retain the plugdev membership with the ConsoleKit
  97 setup.  Armed with this knowledge I moved on to fix the access problem
  98 for the LEGO Mindstorms related packages.</p>
  99
 100 <p>The new system uses a udev tag, 'uaccess'.  It can either be
 101 applied directly for a device, or is applied in
 102 /lib/udev/rules.d/70-uaccess.rules for classes of devices.  As the
 103 LEGO Mindstorms udev rules did not have a class, I decided to add the
 104 tag directly in the udev rules files included in the packages.  Here
 105 is one example.  For the nqc C compiler for the RCX, the
 106 <tt>/lib/udev/rules.d/60-nqc.rules</tt> file now look like this:
 107
 108 <p><pre>
 109 SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0694", ATTR{idProduct}=="0001", \
 110     SYMLINK+="rcx-%k", TAG+="uaccess"
 111 </pre></p>
 112
 113 <p>I suspect all packages using plugdev in their /lib/udev/rules.d/
 114 files should be changed to use this tag (either directly or indirectly
 115 via <tt>70-uaccess.rules</tt>).  Perhaps a lintian check should be
 116 created to detect this?</p>
 117
 118 <p>I've been unable to find good documentation on the uaccess feature.
 119 It is unclear to me if the uaccess tag is an internal implementation
 120 detail like the udev-acl tag used by
 121 <tt>/lib/udev/rules.d/70-udev-acl.rules</tt>.  If it is, I guess the
 122 indirect method is the preferred way.  Michael
 123 <a href="https://github.com/systemd/systemd/issues/4288">asked for more
 124 documentation from the systemd project</a> and I hope it will make
 125 this clearer.  For now I use the generic classes when they exist and
 126 is already handled by <tt>70-uaccess.rules</tt>, and add the tag
 127 directly if no such class exist.</p>
