BTW: the handbook’s CARP-section still shows the old syntax.
I’ve opened a PR for this
http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/186464

The man-page is correct, though.
But the FreeBSD handbook is actually quite good, most of the time, and sometimes contains more examples than the man-pages.

So, I guess a lot of people actually first go to the handbook these days (especially those from the younger generation, who do *everything* in their browser)
;-)

With CARP being so different between 9 and 10, I’d advocate to have both syntaxes reflected in the handbook (if possible).
