Abstracting from the fact that it is usually pronounced as in English, how should the /etc directory be pronounced in Russian?
I was under the impression that since it transliterates to /етц, it should be pronounced "ye te tse". That's the way Дмитрий Молчанов pronounced it in "Администрирование Linux. Лекция 4" at around 18:16, and Anton Pavlenko in "Структура каталогов Linux и монтирование дисков. Как продлить жизнь SSD." at around 10:45.
However, according to my Russian colleagues — also IT specialists — it transliterates to /этц and should be pronounced as "e te tse".
