+	/etc/src.conf now affects only builds of the FreeBSD src tree. In the
+	past, it affected all builds that used the bsd.*.mk files. The old
+	behavior was a bug, but people may have relied upon it. To get this
+	behavior back, you can .include /etc/src.conf from /etc/make.conf
+	(which is still global and isn't changed). This also changes the
+	behavior of incremental builds inside the tree of individual
+	directories. Set MAKESYSPATH to ".../share/mk" to do that.
+	Although this has survived make universe and some upgrade scenarios,
+	other upgrade scenarios may have broken.
