Tinderboxes have always had to cope with this (in the past that mostly
just affected me).  Sometimes when a new CURRENT is forked you can get
away with running the previous version for a while longer because the
kernel ABI usually only diverges slowly.  Eventually there is always
an incompatible change and tinderbox machines must be upgraded to run
CURRENT.  This is just the price of progress.

As a bonus, you get to help with QA of FreeBSD-CURRENT, which you'll
be thankful for in the long run since you'll be using that branch
sooner or later no matter what you do.
