It would be extremely surprising to me if fsck wasn't recognized to be tongue-in-cheekly profane when it was originally named. It could easily have been called ckfs, chkdisk (as it was on other systems), etc. Fsck first appeared on Version 7 UNIX, which means it dates to the early 80s, long after "fuck" had been established as one of the most popular profanities in English. It's context of usage, when the filesystem had become corrupt and the administrator was in a state of annoyance or anger, is also suggestive.
