Log:
  MFC UEFI memstick build script
  
  r264935 (gjb):
  
      Add a separate script to build the memstick.img and the
      mini-memstick.img with UEFI support.
  
      As the comments in the file suggest, 1) there must
      be existing ${.OBJDIR}/usr/src/release/{release,bootonly};
      2) TARGET/TARGET_ARCH must be amd64; and 3) it must be
      a vt(4)-enabled kernel with vt_efifb (*not* vt_vga).
  
      This script is not hooked into release/Makefile in any way
      until further testing is complete.
  
  r264992 (nwhitehorn):
  
      Make a dual-boot BIOS/UEFI memstick image. Testing required before
      this gets renamed make-memstick.sh.
  
  r265017 (nwhitehorn):
  
      loader's GPT support on BIOS does not seem to like the root
      filesystem being the last filesystem on the disk for some reason
      when made by this script. Add a vestigial swap partition to allow
      this to boot with QEMU BIOS.

-# This script generates a "memstick image" for UEFI-capable systems.
-#
-# Prerequisites:
-#  - 'make release'
-#  - KERNCONF *must* be VT (or vt_efifb(4) compiled into the kernel)
-#
-# Note:  This only works for amd64, because i386 lacks the EFI boot bits.
+# This script generates a "memstick image" (image that can be copied to a
+# USB memory stick) from a directory tree.  Note that the script does not
+# clean up after itself very well for error conditions on purpose so the
+# problem can be diagnosed (full filesystem most likely but ...).

 # Usage: make-memstick.sh <directory tree> <image filename>
