I just completed an upgrade from a 9/1998 -current to 1/2/1999 elf
-current. The new bootblocks work and the elf kernel works.
Thanks to the core team for the hard work, and especially Mike Smith
for all the help he gave me, and, to Robert Nordier for the bootblock
help.

====================================================
The steps were:
1. Upgrade to the latest -current
cvsup
make world
Note: I used make -DNOGAMES -DNOPERL world to save time and
to get around a missing gv.h. I will look for this
when I do the last make world.
rebuild and install a new kernel
2. make -DNOGAMES -DNOPERL aout-to-elf
Again, time and gv.h
actually, I used aout-to-elf-build and aout-to-elf-install
It would be nice if Makefile.upgrade told the world it was
successful, after touching the /usr/obj/do* file.
3. reboot.
4. install the new bootblocks.
cd /sys/boot
make sure 'objformat' returns elf
if necessary, setenv OBJFORMAT elf
make all install
disklabel -B -b /boot/boot1 -s /boot/boot2 da1
5. reboot
6. build a new kernel and install it
cd /sys/compile/<kernel name>
make clean
make KERNFORMAT=elf depend
make KERNFORMAT=elf
mv kernel kernel.elf
install -c -m 555 -o root -g wheel -fschg kernel.elf /
7. reboot
The first time through, I booted kernel
reboot
This time, I booted kernel.elf
I can build and execute elf's.
# g++ hello.cpp -o hello
# file hello
hello: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD),\
dynamically linked, not stripped
I have 3 steps left, but, they should be easier. At least I
understand these.
8. make world to be sure all the problems are out of the sources.
9. rebuild and install an elf kernel, to catch-up after 8.
10. rebuild all the ports and applications... to convert to elf.
Are there any tools to catch all the ports that are installed
and rebuild them? I planned to go through /var/db/pkg. There
are some duplications, like XFree86-3.3.1 and XFree86-3.3.2.
If I create a tool, based on /var/db/pkg or pkg_info, I will
send it along.
