svn revision in uname

[Anders N.]

Hi. I've noticed in my "uname -a" on 9.1-RELEASE there is "r243826." This is on a system that upgraded from 9.1-RC3 using freebsd-update (binary). On another system, upgraded from 9.0-RELEASE via freebsd-update (source), there is nothing at all and uname -a looks normal. Two other people I asked have r243825 (installed from ISO) and r243872 (upgraded from svn).

They're all 9.1-RELEASE, shouldn't they be the same, final version?
