It would be convenient if, before csup disappears, the 'Sychronising
your Source' section in the Handbook could be updated to contain
instructions for updating *just the source* using freebsd-update. Even
if this is as simple as 'Components src' it would be good to state that
explicitly; it would also be useful to give a procedure for moving from
a csupped tree to one which freebsd-update will be able to apply deltas
to, if that's possible without redownloading the whole source tree.

In general, it's not terribly clear to me what will happen if I run
freebsd-update on a system I have built from source. How does it know
where to start from when it downloads deltas: does it assume `uname -r`
accurately reflects the exact current state of the system? What will
happen if I patch my source and then run freebsd-update without
reverting those changes: will it revert them for me, like csup did, will
it make a mess, or will the update fail?

It would also be better, IMHO, to change the language in that section to
recommend freebsd-update for those running RELEASE branches, and reserve
the svn recommendation for those tracking development branches.
