I would absolutely expect a sysadmin in particular to know and understand the term and acronym.

Well I would expect a sysadmin to have already been following the kernel mailing lists and not even need to look at copy.fail.

In fact, why do people even write stuff down? Everyone should just know everything.

It's still just courteous to define acronyms on first use, it doesn't take any real effort to do that.

[a96]

Very much true, and I would never criticize that. Just that this term would be particularly obscure to a sysadmin which seems completely backwards.

Understanding a term with the help of context is very different from guessing what the letters of an acronym might mean. The latter is more like a crosswords puzzle, and a totally unneccessary task for the reader.
