Understanding Membership Structures in Debian and Ubuntu

Debian and Ubuntu have a set of official membership roles that can be granted to regular contributors. Those roles come with rights that enable the contributors to do their work and to participate in the project governance (elections and other official decision-making processes). It’s also a way for the distributions to acknowledge the work done: most contributors are proud of the status they reached.

The membership structure plays an important role in the development of a distribution: it defines the kind of contributors that are welcome in the project, it sets expectations of the project towards its contributors and defines their rights. In the end, this shapes the project’s ability to recruit new contributors to keep the project alive and kicking. This article introduces the existing statuses in Debian and Ubuntu, and defines the — sometimes confusing — jargon associated with them.

The Debian Case

Debian only has two types of official members: Debian Developers (DD) and Debian Maintainers (DM). The rights of the developers are codified in the Debian Constitution while those of the maintainers have been defined in a general resolution of 2007. The Debian Maintainer status is still mostly documented in a wiki page. The integration of this new status in Debian’s official processes has been slow to come largely because it was introduced — at that time — without enough negotiation with the involved parties. Nowadays, it is preferred that people get the DM status before applying for DD.

DM is a very limited role: maintainers can only upload packages that already have their name on them (either in the Maintainer or Uploaders field) and a specific flag (DM-Upload-Allowed: yes) that only Debian Developers can add. They have no other rights and limited access to Debian’s resources.

Besides those official roles, there are also maintainers of packages that have no official status within Debian except that they are listed in the “Maintainer” field of the package. They are doing the maintenance work but all uploads are done by a Debian Developer after verification of the work done (this is called “sponsorship” and is the only way to start with official packaging work). Once the DD trusts the maintainer, the developer will typically ask the maintainer to apply for DM status in order to be relieved from the sponsorship work.

In the end, that makes three different kind of package maintainers and a lot of confusion when you discuss membership issues… in particular when the New Maintainer process is the path that you follow to become a Debian Developer. Don’t be fooled by the names when reading Debian’s documentation!

The Ubuntu Case

Ubuntu had, from the start, an official Ubuntu Member status that includes all contributors: developers of course, but also documentation writers, artists, translators, etc. This status notably grants the right to vote in elections of the Community Council, the right to participate on Planet Ubuntu, and the @ubuntu.com email alias.

For developers, the situation is more complicated: the wiki page lists no less than five different statuses. Initially, developers were split between Ubuntu Core Developers and the MOTU (Masters Of The Universe). The latter were responsible of the universe/multiverse sections of the archive while the former also had upload rights for the main/restricted sections. But, inspired by the Debian Maintainers concept and facing concrete problems in terms of archive management, they changed their infrastructure to offer more fine-grained control on package uploads.

Ubuntu can now grant upload permissions on a package-per-package basis, but it can also delegate the right to grant upload permissions with the same granularity. This lead to the new Per-Package Uploader status which is simply an Ubuntu Member with upload rights on a limited set of packages where they have a specific expertise. The more generic Ubuntu Developers status now encompasses members of various development teams that have been delegated the right to manage upload permissions on a (usually large) package set (the current teams are Ubuntu Desktop, Mythubuntu, Kubuntu, and Edubuntu). Those teams can define their own policy to add new members provided they follow the basic rules defined by the Developer Membership Board (see this wiki page).

Ubuntu Contributing Developer is an intermediate status for someone who is not yet ready for one of the other developer statuses but who has still shown enough commitment to be an Ubuntu Member.

All those statuses can be obtained in a similar way: you prepare a wiki page listing your past contributions, you collect testimonials from existing members that you have worked with, you add yourself in the agenda of the next meeting of the board (or council) that grants the status that you seek, and you attend the meeting. The members of the board will decide whether you are ready for the status (or not) based on what you provided in the wiki, based on your answers during the meeting (and on a mailing-list for developers), and based on what others have to say about you.

The most important boards are usually elected by the community while others are commonly appointed by the community council. Those governance bodies include Canonical employees but not as many as one would expect: two out of eight in the Developer Membership Board, two out of eight in the Community Council, but all six members of the Technical Board. The last figure, while not intended, is not surprising given the high expectations set on potential members of the technical board. Mark, as the founder, is the only person to have a permanent seat on both the Community Council and the Technical Board.

Comparison of the Statuses Between Debian and Ubuntu

The following table summarizes the rights given to each developer role in the two projects (Put the mouse over the abbreviations to know what they are referring to).

Rights Debian Ubuntu
Package maintenance via sponsorshipYN/AYYYN/A
Official email alias-YYYYY
Participate in votes for members-YYYYY
Participate in votes for developers-Y-YYY
Upload rights restricted to pre-approved packagesY--Y--
Upload rights restricted to a section of the archive----Y-
Unlimited upload rights-Y---Y
Number of contributors (as of 2010-07-27)117904462278563

Please note that the number of contributors are not 100% accurate for Ubuntu. A contributor can have multiple statuses (direct membership to a launchpad group) granted over time (while gaining experience). The problem has been mostly avoided by calculating differences between number of members of the various groups but it’s not perfect and it can’t be: some MOTU are also PPU for packages in main and it’s legitimate (but I only counted them as MOTU and not as PPU). Another limitation is that members of some administrative teams are included indirectly in many teams and thus appear in the count while they should not.

Anyway, this simple table makes it obvious that Ubuntu’s structure offers a broader choice of statuses. They acknowledge the work of all contributors from the start while still giving the most critical rights only to those who have proven that they deserve them. Despite this difference, Debian still has a significant advantage in terms of number of developers. That number does not tell the whole story though: the Ubuntu contributors include many Canonical employees (e.g. 36 out of 63 core developers have a @canonical.com email registered on their launchpad account) that are likely to spend more time working on the distribution than the average Debian member. But even if comparing person-hours would be a challenging thought experiment, in practice it’s of not much interest if both projects continue to cooperate and if more and more of the contributions flow in both directions.

Debian is aware of the shortcomings of its structure. Changes to better accommodate non-packagers have been discussed several times already. The last efforts in that direction were unfortunately perceived as a solution ready to go rather than a proposal to be discussed, and the project got quickly buried by a general resolution (GR). Even if that resolution invited for further discussion and a new proposal, the truth is that when someone’s initiative is “corrected” by way of GR, it usually kills any motivation to go forward.

Possible Evolution?

On the Ubuntu side, the infrastructural changes were completed recently and they don’t expect any further change in the near future. They do plan, however, to expand usage of those new features so that more teams benefit from the possibility to control upload rights on packages that are relevant to them, and so that more individuals developers apply to become Per-Package Uploaders on packages that they know very well.

On the Debian side, a recent discussion on the debian-project list brought back the topic of the bad terminology and it was agreed that the “New Maintainer process” should be renamed into something else (“New Developer process” has been suggested). But Christoph Berg — Debian Account Manager and hence heavily involved in the New Maintainer Team — suggested that Debian would be better off implementing the long-awaited membership changes before trying to update all the documentation. It would certainly imply some more vocabulary updates. Later in the discussion, he confirmed that membership reform is on the top of the TODO list of the new maintainer team (just after the rewrite of the nm.debian.org website).

What can be expected from this reform? The following answers are my own guesses based on my experience of Debian, but the project hasn’t decided anything yet.

  • First of all: a new status for contributors that are not packagers. The tricky part will be defining the process to follow and the rights granted.

  • Changes to the technical implementation of the DM status. The current implementation does not allow to give upload rights to a single DM if two are listed in the Uploaders field of a package (and both might not have the same experience for that package). Furthermore, it suffers from annoying restrictions like the inability to upload new binary packages.

  • A change of the Debian constitution to integrate those new statuses is almost unavoidable.

  • Other more invasive changes have been proposed like replacing the NM process by a simple designation by other DD, but it’s unlikely to happen. The NM process can already be greatly simplified by the application manager if the applicant can show good testimonials from other developers and if he has a track record of real contributions (e.g. as witnessed by changelog entries in Debian packages).

Almost two years have elapsed since the previous efforts in that direction, the new maintainer team has recruited new members and is in a general better shape. Hopefully, the next episode of this saga will have a better outcome.

How to make 110.28 EUR in one month with free software and Flattr

Flattr FOSS Logo

  1. Create an account on Flattr.com (mine is here);
  2. Submit the URL of your free software project to the Flattr directory with a good description and the proper tags (here’s my entry for dpkg);
  3. Add a Flattr button on your website (I put one on wiki.debian.org/Teams/Dpkg);
  4. Inform your users and reach out to free software users using Flattr by registering your project in Flattr FOSS.

And I’m not alone, Joey Hess made 25 EUR in one week only.

And right now only 30K people are using Flattr. I expect this number to increase significantly now that invites are no longer required to open a Flattr account (see the announce on Flattr’s blog).

It’s time to spread the word about Flattr FOSS!

First Flattr FOSS Suggestions

Flattr FLOSS LogoThe Flattr FOSS project is quite young so very few free software are currently listed in the dedicated directories. It’s still advocacy time: if there are free software that you’d like to flattr, please tell them and point them to Flattr FOSS.

It’s too early for any conclusion, but the feedback from users is good and it looks like that people using flattr to support free software are more generous than the average flattr user. You’re great people! :-)

Anyway, it’s time for me to give a few suggestions of projects to flattr.

  1. My first recommendation is Project Hamster, it’s a time-tracking application for GNOME but it has come a long way thanks to the work of Toms Bauģis. I use everyday and it rocks.
  2. My second recommendation is Överallt, it’s a Firefox extension that allows usage of Flattr even in places where it was not designed to be used: forums, mailing list archives, etc. The persons using Flattr just put [Flattr=20693] in their signature and the Firefox extension automatically replaces this text with a real Flattr button ready to be clicked. Thanks to Paul Da Silva for the nice idea and the first implementation!
  3. My third recommendation is Mustard, it’s a StatusNet client for the Android platform. More concretely you can install it on your Android phone to send updates to identi.ca while traveling. I have no Android phone but Mustard seems to be popular among owners of such phones!
  4. My fourth recommendation is moreutils from Joey Hess. It’s set of unix (command line) tools that “nobody else thought of writing when unix was young” (according to Joey himself). They are all very useful, I use more or less regularly isutf8 (verify if a file is UTF-8 compliant), combine (logical operations on lines of two files), pee (send standard input to two programs, very useful in git hooks when you want to run two programs that both consume the same data), sponge (ever tried “grep -v foo file >file” and lost your data? now you can use “grep -v foo file | sponge file”). And Joey is a long time Debian developer who has truly shaped Debian, he’s behind several major Debian projects (debconf, debian-installer, debhelper, …). Big kudos to him!
  5. My last recommendation is to flattr Andreas Gohr for his work as dokuwiki lead developer. There’s no flattr button on dokuwiki’s website but you’ll find some in Andreas’ blog, just pick a dokuwiki related article like this one: Dokuwiki Birthday Bughunting Weekend. Dokuwiki is a simple wiki that works without any database (the pages are stored in flat files) and it’s even commonly used to setup simple websites thanks to the numerous themes available.

Okay, that’s it for this month. I’ll try to keep a broad panel of software (desktop, command line, mobile, web, etc.). Since I have promoted a GNOME desktop application, I would like to be able to promote a KDE or XFCE application next month but I did not discover any KDE/XFCE project using Flattr… do you know any? Please share in the comments if you find some.

Also I wonder if you have decided of a flattr strategy… Personally I’m likely to flattr my favorites projects/persons each month and to flattr a few other occasionally as I discover them. What’s your own strategy?
