Writing about containers and jails today for #openzfsmastery. Language management is a big part of writing a tech book. Techies are both notoriously bad at language, and notoriously picky about it. Containers and jails are types of lightweight virtual machines. I don't want to keep repeating "lightweight virtual machines" multiple times in a paragraph, so I need a good short punchy word. I could abbreviate and call them LVMs, but Linux folks have different associations for that abbreviation. The current attempt is to call them "lightweight virtual machine instances" 2-3 times to build an association in the reader's brain, then call them "instances" for the remainder of the chapter. It wouldn't work for a longer piece, but I think I can get away with it for half a chapter.
