Ah.  That's why then.

svnup does not record the revision in the way that can be reported by

Specifically, sys/conf/newvers.sh calls svn{,lite}version, which walks
the tree to generate the output for uname(1).

No, when kernel/userland are out of sync, you will still see the svn
revision.  It will not be accurate, though.

(freebsd-version(1) in head/ is able to differentiate when userland and
kernel are out of sync to provide actual useful output; also uname(1)
was updated today with r256557 to add '-K' and '-U' options for kernel
and userland, respectively.)

Well, 10.0 is the immediate focus; 11.0 will not exist as a release for
about 2 years or so.  stable/9 will continue to receive updates.  The
number of updates merged to stable/8 will surely lessen, but do not
expect any more 8.x releases.

It is an illusion.
