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.

Technically, this is also possible by creating extra groups, but this kind of access control presumably exists because the old-school method can be a pain to administer. Choosing group names can also be an "interesting" secondary challenge.
i.e. Dude's not going to be best pleased if they
ls -land see the group on the file isxyzgroup-but-not-dudeeven if it is with good reason. (Shouldn't have deleted the database, dude.)I don't really think that that's a realistic goal for ACLs. I mean,
getfaclshowing the user specifically being excluded probably isn't any more-polite.In a previous life (in the 90s) I was a un*x sysadmin, and ACL is nightmarish in big company, I hated it and avoided it
