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.

Linux has similar fields for realName, emailAddress, location, timezone and more. But like birthdate, I think they're all optional.
Was Linux ever used for massive multiuser systems? I thought it had always been primarily home use and internet servers. I think big multiuser systems went out of fashion with Solaris. Well, I suppose corporate workstations need user accounts where some of these are set.
No Linux as such was not, by the time Linux got popular the big multiuser systems were on their way out. I still worked on those in college. But they were SGI, HP-UX and Sequent. Especially the latter were huge systems.
But these fields were just a clone of what was in the original Unix systems.
