I know that's the theory, but I've just noticed it doesn't seem to work 
in practice. On the one machine I have that has /usr/src I switched to 
using freebsd-update in late 2014. In freebsd-update.conf I have

10.1-RELEASE-p10
10.1-RELEASE-p13

I.e. my source hasn't updated in well over a year, although the various 
bin and lib directories show updates from this month. Could this be due 
to this message

# freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 5 mirrors found.
Fetching metadata signature for 10.1-RELEASE from update6.freebsd.org... 
done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

The following files are affected by updates, but no changes have
been downloaded because the files have been modified locally:
/var/db/mergemaster.mtree

No updates needed to update system to 10.1-RELEASE-p13.

and is there any way to fix it? Yes, I know I can get the source from 
svn but as I'm using freebsd-update it shouldn't be necessary.
