EC The European Commission insists on ● Open Source ● Open Standards "For all new development, where deployment and usage is foreseen by parties outside of the Commission Infrastructure, Open Source Software will be the preferred development and deployment platform." (2008) – http://ec.europa.eu/idabc/en/document/740 3/469

3. Definitions ● FOSS - Free and Open Source Software ● Distro - an operating system distributed as packaged set including – a kernel – device drivers, – file systems, – utilities and – sometimes user applications ● Stable - not changing

4. Stable ● Kernel ● modules ● drivers ● Programs ● version Same programs ● e.g. Firefox Same versions of the programs ● e.g. KDE 3.5.x Goal met: 100% predictable

5. Support Cycle ● Development ● Release ● Maintenance ● EOL Release Stable Devel

6. Development Release Stable Devel Release Stable Devel Release Stable Devel v1v1 v2v2 v3v3 etc Release Stable Devel

7. Definitions ● Patch – repairs or addresses a specific problem without otherwise changing functionality or behavior. ● Upgrade – essentially a new package with possible changes in functionality, behavior, appearance, price or licensing.

8. OpenBSD Development There are three "flavors" of OpenBSD: ● -release: The version of OpenBSD shipped every six months on CD. ● -stable: Release, plus patches for security and reliability. ● -current: Where new development work is done. Eventually, it will become the next release. Release Stable Current Release Stable Current

9. Debian Development There are three "flavors" of Debian: ● -stable: The released and supported version, with patches for maintenance and security ● -testing: In queue to become "stable", packages selected, but maybe not all arch. ● -unstable: Where new development work is presently being done, and eventually, it will turn into the next testing. StableTesting Unstable StableTesting Unstable

10. Ubuntu ● Ubuntu is built from Debian-testing
