From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What’s wrong with implementation inheritance? Don’t you want that?
Generally no. As soon as a class hierarchy becomes moderately complex, implementation inheritance makes code very hard to maintain, because you need to read the whole stack of classes to see what a single change will actually do.
Rust has another system, traits and trait implementations.
The consensus seems to be that implementation inheritance leads to code that is difficult to understand and difficult to reuse. Its perhaps the main reason C++ is banned from the kernel.
