About the LSB

When targeting Linux as a platform, application developers want to have some assurance that the code they write on one Linux distribution will run on other Linux distributions without having to go through extra effort. This matches their experiences on other popular platforms, such as Windows or Mac OS X.

The LSB workgroup is pleased to announce the immediate availability of the Linux Standard Base (LSB) version 4.1.

As of this writing, there are two known issues with the release candidate:

  • The decision to promote xdg-utils out of trial use was made after the latest draft of the specification; therefore, the current RC spec continues to list it as trial use.

Linux Standard Base (LSB)

The Linux Standard Base was created to lower the overall costs of supporting the Linux platform. By reducing the differences between individual Linux distributions, the LSB greatly reduces the costs involved with porting applications to different distributions, as well as lowers the cost and effort involved in after-market support of those applications.
