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.

That is not actually true. glibc hasn't changed ABI versions in a backwards incompatible way in a long time. You can't use new binaries on the old system usually but you can absolutely use old ones on the new system.
Many other libraries do change ABI versions more frequently though.
Okay, fair point, thanks for clarifying that. I just know glibc versions have bitten me before :(
It is frequently a problem when running old systems and binaries are compiled for something newer, especially with distros like RHEL that "support" stuff for much longer than most upstream projects are willing to wait to use new features.
