+# The ports for which the base OS binaries will be included.
+# MACHINE_ARCH shared distribution directories and the "ALL" shared
+# distribution directory are added automatically where needed.
+#
+# The following ports, if included, will be bootable on their respective
+# CD images:
+#
+#     alpha, i386, macppc, pmax, sparc, sparc64, sun3, vax.
+#
+# Special notes on booting:
+#
+# * macppc and mac68k will cause the inclusion of HFS partition and
+#   filesystem info on the CD, with automatic MacBinary probing and encoding.
+#
+# * alpha and macppc cannot boot on the same disc.  This will cause a warning
+#   in the build, and macppc will override.  This will be fixed by a better
+#   installboot for alpha in the future.
+#
+# * macppc and vax cannot boot on the same disc.  These platforms use the
+#   same locations in block 0 to store boot information.  This will cause a
+#   warning in the build, and macppc will override.
+#
+# * sparc64 cannot boot using default boot arguments on the same disc as
+#   the sun3x model of sun3.  These platforms use the same partitions
+#   in the Sun boot map by default.  This will cause a warning in the build,
+#   and sparc64 machines will have to boot with "boot cdrom:g" instead of
+#   "boot cdrom".
