documents; this is no longer the case. 15.4.2.3. Accepting the Principles These administrative formalities are followed with philosophical considerations. The point is to make sure that the candidate understands and accepts the social contract and the principles behind Free Software. Joining Debian is only possible if one shares the values that unite the current developers, as expressed in the founding texts (and summarized in Chapter 1, The Debian Project (page 2)). In addition, each candidate wishing to join Debian ranks is expected to know the workings of the project, and how to interact appropriately to solve the problems they will doubtless encounter as time passes. All of this information is generally documented in manuals targeting the new maintainers, and in the Debian developer's reference. An attentive reading of this document should be enough to answer the examiner's questions. If the answers are not satisfactory, the candidate will be informed. He will then have to read (again) the relevant documentation before trying again. In the cases where the existing documentation does not contain the appropriate answer for the question, the candidate can usually reach an answer with some practical experience within Debian, or potentially by discussing with other Debian developers. This mechanism ensures that candidates get involved somewhat in Debian before becoming a full part of it. It is a deliberate policy, by which candidates who eventually join the project are integrated as another piece of an infinitely extensible jigsaw puzzle. This step is usually known as the Philosophy & Procedures (P&P for short) in the lingo of the developers involved in the new maintainer process. 15.4.2.4. Checking Skills Each application to become an official Debian developer must be justified. Becoming a project member requires showing that this status is legitimate, and that it facilitates the candidate's job in helping Debian. The most common justification is that being granted Debian developer status eases maintenance of a Debian package, but it is not the only one. Some developers join the project to contribute to porting to a specific architecture, others want to improve documentation, and so on. This step represents the opportunity for the candidate to state what they intend to do within the Debian project and to show what they have already done towards that end. Debian is a pragmatic project and saying something is not enough, if the actions do not match what is announced. Generally, when the intended role within the project is related to package maintenance, a first version of the prospective package will have to be validated technically and uploaded to the Debian servers by a sponsor among the existing Debian developers. COMMUNITY Sponsoring Debian developers can “sponsor” packages prepared by someone else, meaning that they publish them in the official Debian repositories aer having performed a careful review. This mechanism enables external persons, who have 426 The Debian Administrator's Handbook
not yet gone through the new maintainer process, to contribute occasionally to the project. At the same time, it ensures that all packages included in Debian have always been checked by an official member. Finally, the examiner checks the candidate's technical (packaging) skills with a detailed questionnaire. Bad answers are not permitted, but the answer time is not limited. All the documentation is available and several tries are allowed if the first answers are not satisfactory. This step does not intend to discriminate, but to ensure at least a modicum of knowledge common to new contributors. This step is known as the Tasks & Skills step in the examiners' jargon. 15.4.2.5. Final Approval At the very last step, the whole process is reviewed by a DAM (Debian Account Manager). The DAM will review all the information about the candidate that the examiner collected, and makes the decision on whether or not to create an account on the Debian servers. In cases where extra information is required, the account creation may be delayed. Refusals are rather rare if the examiner does a good job of following the process, but they sometimes happen. They are never permanent, and the candidate is free to try again at a later time. The DAM's decision is authoritative and (almost) without appeal, which explains why the people in that seat (currently, Jörg Jaspert, Christoph Berg and Enrico Zini) have often been criticized in the past.
