As I understand it, the revision ID refers to the whole repository, not
just a branch. So if you do your own svn checkout tomorrow, you'll get
yet another revision number, even though the files will (probably) be
completely identical to what you checked out yesterday -- ongoing
commits to HEAD will keep kicking the revision number up.

There is work going on to make system builds completely, bit-for-bit,
repeatable, but that will presumably mean getting rid of this revision
number information, not making it consistent.
