This section describes how to "read" a given LayManSys version number, because this number tells us a lot about the package numbered this way. The section covers information about major, minor and bugfix releases as well as stable and development packages.

LayManSys Versioning System

LayManSys uses the so-called Linux Kernel Versioning System, that means, if you have a certain release number, you can see directly, if the package is a stable or a development one. This versioning system is not difficult to understand: A version number consists of three numbers, each delimited by a dot . They are ordered by major version, minor version and patch level, e.g.

Example 1. The Versioning System Formally


where M means the major number, m stands for the minor number and p is the patch level. All three numbers have at least one digit, so

Example 2. Versioning Example


is a valid version number.

The Linux Kernel Versioning System also differs between stable and (maybe unstable) development releases. Stable versions, that are made for production systems have an even minor version number, development packages an odd one.

LayManSys Specific Notes

LayManSys consists of several packages that are developed independently from each other. To show you which packages work or belong together, you only need to have a look at the major and minor version numbers: If they are the same, both packages work together. The patch level, as stated by the name patch level only helps to find the latest, patched release. To make things clear, guess you have to following two packages downloaded:

Example 3. Two Packages with Matching Version Number

Take their major and minor version numbers, which is in both cases 0.1 and compare them: In this case, they are the same, that means, both packages work together. But in the following example, you may get into trouble when using LayManSys:

Example 4. Two Packages with Version Numbers not Matching

The reason for your possible problems is easy: Take their relevant version numbers 0.2 and 0.1 and compare them, but this time, they are not equal.

With the information above in your mind, you can now go to the LayManSys Download Page for getting the latest release. The next chapters describe, how to setup up a working LayManSys installation and how to customize it for your needs.

Versioning and CVS

Each LayManSys release can also be found in the CVS repository; the releases are tagged using the following schemata:

General LayManSys Releases (which major updates)

Version_M_m_p, e.g.

Beta Releases

Beta_YYYY_MM_DD, where YYYY stands for the year, MM for the month and DD is the release day, e.g.

Single Releases of Certain Packages

PACKAGE_M_m_p, where PACKAGE stands for the (CVS) package with a starting uppercase character, e.g. there is a release tagged


The word before the first underscore is written exactly like this, while M_m_p is the release number as described above.
