Good question, not silly.  The answer is I don't know -- when I moved
from RELENG_9 to RELENG_10, I reinstalled straight from memstick here:

ftp://ftp4.freebsd.org/pub/FreeBSD/snapshots/amd64/amd64/ISO-IMAGES/10.0/

I always install -STABLE and not -RELEASE because for nearly 15 years
I've found too many broken things in -RELEASE that don't get fixed soon
enough for me.

I can try "rolling back" in SVN to r256281 and try that (I'm afraid to
find out what buildkernel/buildworld will break on though, heh).  I
think that's the rev as close to 10.0-RELEASE as possible?
