You should be able to do a buildworld, buildkernel, installkernel,
installworld sequence from a FreeBSD-4.x machine. The installworld
should be able to proceed through without blowing up. But if you
do a partial installworld you can end up in a no-win situation
you won't be able to rebuild the world with a FreeBSD machine and
DragonFly includes. Once the world is installed I would also
running the 'upgrade' target, which will clean up the RC files, a
chunk (but not all) of the stale binaries left over from FBsd,
and most of /etc, before doing mergemaster.
The safest route is to burn the DragonFly CD ISO we have
our site and to blow away your disk. Even if you decide to try
to install over FreeBSD instead of blowing away the disk having a
DragonFly CD lying around can be extremely useful if you get stuck.
Also, if you burn a DFly CD, you can boot it without messing with
hard drive to make sure that DragonFly supports your machine's
