I blame google for the existence of this entire thread.
When I type "define:canonical" into google, it only displays the those
"Eucharistic" themed definitions, not the mundane synonyms (such as
those ones Paul cited). Also had I typed "canonical" on it's own
(without "define:") I would have seen the wikipedia page for "canonical"
Canonical is the adjective for canon, literally a 'rule', and has come
to mean also 'standard', 'archetypal', 'typical', or 'unique
Which then makes a lot more sense for this term.
Thanks to all who chimed in, I also understand what Evan meant when it
pointed out the distinction of what calling it "ALIAS" would have meant.
I'm still happy to have found out about the origins of the word in a
technology context that was sent to me offlist, about it being in the
K&R C book.
