There was a thread on this a few years back when we only had the
-CURRENT and -STABLE branches.  The problem at that time was that when
code was being back ported from -CURRENT to -STABLE it would break
production machines that had been updated to the latest -STABLE code.

The solution was to create the -STABLE security branches where only
security and minor fixes were applied.

The handbook needs a new section added to:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html

which details what the -STABLE security branches (RELENG_x_y) are to
be used for.

23.2.2.3 What are the FreeBSD-STABLE security branches?

If you are interested in tracking the security of the current STABLE
-RELEASE, then you should consider following the FreeBSD-STABLE
security branch.

The FreeBSD -STABLE security branches tracks only security and minor
fixes relating to the currently supported STABLE -RELEASES. No major
changes are made to these branches.

Although we endeavor to ensure that the FreeBSD-STABLE security branch
compiles and runs at all times, this cannot be guaranteed. <Re-write?>

We do not recommend that you blindly update any production servers to
FreeBSD-STABLE security branch without first thoroughly testing the
code in your development environment.

To use the -STABLE security branch you need to check out the FreeBSD
sources using the RELENG_x_y tag.
