ubuntu and debian relationship

Packages that have been modified in both Debian & Ubuntu get I always liked this little picture about linux distributions and their relations.:). All of the relationship fields can only be folded in source package control files. For build relationship fields (Build-Depends, Build-Depends-Indep. Ubuntu tends to favour new technology over stability, where Debian prefers stability over the latest features What are the relations between Debian and Linux?.

Debian might not be better for everybody but there are many reasons why one could prefer Debian over Ubuntu.

He listed some of them: On the other hand, Ubuntu is under control of Canonical where some decisions are imposed, it advocates some proprietary web services Ubuntu Onethe installer recommends adding proprietary software, and copyright assignments are required to contribute to Canonical projects.

Debian is also better in terms of quality because every package has a maintainer who is often an expert in the field of the package. In conclusion, Lucas explained that Debian can neither ignore Ubuntu nor fight it.

During UDS-M the previous summitthis increased involvement from Debian was a nice surprise to many. Stefano Zacchiroli—the Debian leader—collected and shared the feedback of Debian developers and the session ended up being very productive.

Six months later is a good time to look back and verify if decisions made during UDS-M see blueprint have been followed through. Ubuntu has updated its documentation to prominently feature how to cooperate with Debian.

For example, the sponsorship process documentation explains how to forward patches both to the upstream developers and to Debian. It also recommends ensuring that the patch is not Ubuntu-specific and gives some explanation on how to do it which includes checking against a list of common packaging changes made by Ubuntu. The Debian Derivative Front Desk is mentioned as a fallback when the Debian maintainer is unresponsive. Launchpad has also been extended to provide a list of bugs with attached patches and that information has been integrated in the Debian Package Tracking system by Lucas Nussbaum.

Still some work to do Some of the work items have not been completed yet: Another issue concerns packages which are first introduced in Ubuntu. Most of them have no reason to be Ubuntu-specific and should also end up in Debian. It has thus been suggested that people packaging new software for Ubuntu also upload them to Debian. As with any important policy change, it can take several years until people are used to it.

This time the UDS session was probably less interesting than the previous one. Stefano explained once more what Debian considers good collaboration practices: He also invited Ubuntu to discuss big changes with Debian before implementing them. An interesting suggestion that came up was that some Ubuntu developers could participate in Debcamp one week hack-together before Debconf to work with some Debian developers, go through Ubuntu patches, and merge the interesting bits.

There was also some brainstorming on how to identify packages where the collaboration is failing. A growing number of Ubuntu revisions identified for example by a version like 1. If Ubuntu consistently has a newer upstream version compared to Debian, it can also indicate a problem: Few of those discussions led to concrete decisions. It seems most proponents are reasonably satisfied with the current situation. Of course, one can always do better and Jono Bacon is going to ensure that all Canonical teams working on Ubuntu are aware of how to properly cooperate with Debian.

The goal is to avoid heavy package modifications without coordination. Conflicts between individuals still happen, but there are multiple places where they can be reported and discussed debian-ubuntu channel, Derivatives Front Desk at derivatives debian.

Debian vs. Ubuntu: What's the Difference?

Documentation and infrastructure are in place to make it easier for volunteers to do the right thing. Despite all those process improvements, the best results still come out when people build personal relationships by discussing what they are doing.

I thought they shared no code? Windows NT was developed to be a "real" modern, preemptive, multi-user, multi-tasking secure operating system.

A kernel provides a platform for programs to run, in the case of Unix, it allows multiple programs to run on a single computer and multiple users to access it. A kernel runs no programs on its own, these must be separately developed and provided.

An API is a standard way for programs to talk to the kernel. It's part of the kernel.

An operating system is a kernel plus common utility programs to manage and administrate the system. Common utility programs for UNIX include basic programs that manage services and logins inita shell that allows you enter commands sh, bashand basic file management commands such as cp, ls, mv, etc.

Debian is a Linux distribution. It started in and is among the oldest distributions. Linux distributions generally provide: It's different from Windows where traditionally software has been distributed on CDs and years go by between versions and updates.
