+This release uses the ELF binary object format. Existing (a.out) binaries
+can still be used on your system after it has been upgraded, provided
+that the shared libraries needed by those binaries are made available
+in the filesystem hierarchy rooted at /emul/aout.
+
+This upgrade procedure will now establish this hierarchy by moving all
+shared libraries in a.out format found in /usr/lib to /emul/aout/usr/lib.
+It will also move the X11 shared libraries in a.out format from previous
+NetBSD/sparc X11 installation sets, if they are installed.
