You could get almost the same effect by building a kernel with
COMPAT_AOUT. It's not as pretty, because it does wierd things to
shells, but if you've already updated your shells it should be

The source is already in the tree, and it really does work -- I
converted a 1.5_ALPHA/i386/a.out system to 1.5_ALPHA/i386/ELF last
weekend, everything works fine, and the final packages are in the
process of being rebuilt now (while running under X with a.out GNOME).
You just can't build with an ELF toolchain. If anyone else is
contemplating upgrading from source, remember to build a new
with your old toolchain first, and also save (rename) your old
ldconfig and ldd.
