Subject: [PATCH] Add script to setup bootable CD ISOs for both BIOS and EFI
 systems. Tested and working on QEMU. Actually using this script as the
 regular image generator, like with the memstick one, will require that the
 kernel support EFI too. In particular, the following two things are required:
 1. vt(9) be the default console driver 2. vt_efifb and vt_vga be able to
 coexist usefully in the same kernel

One other note here is that this requires newfs_msdos and mdconfig, which is
really ugly. NetBSD's makefs at least seems to support FAT now. If that
actually works, it should be imported and we can get rid of the mdconfig mess.

+# This script is used by release/Makefile to build the (optional) ISO images
+# for a FreeBSD release.  It is considered architecture dependent since each
+# platform has a slightly unique way of making bootable CDs.  This script
+# is also allowed to generate any number of images since that is more of
+# publishing decision than anything else.
+#
+# Usage:
+#
+# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
+#
+# Where -b is passed if the ISO image should be made "bootable" by
+# whatever standards this architecture supports (may be unsupported),
+# image-label is the ISO image label, image-name is the filename of the
+# resulting ISO image, base-bits-dir contains the image contents and
+# extra-bits-dir, if provided, contains additional files to be merged
+# into base-bits-dir as part of making the image.
