NOTE:  the information below is only relevant to people who will be
upgrading to NetBSD-current after the sup tree reverts back to the
trunk.  but it is *very* relevant for those people.

there are two things in the kernel configuration land that you will
need to be aware of, if you are using NetBSD-current.

your kernel configuration files will need to have this line added
to them:

include "arch/sparc/conf/std.sparc"

this includes support for EXEC_AOUT, which is now required in the
kernel configuration file.  if you use COMPAT_SVR4, you will also need
to add EXEC_ELF32, or solaris executables will fail.


and if you do not update your userland before the kernel, you will
also need

options	COMPAT_12

or your shutdown/halt/reboot will fail.
