/usr/src/sys/i386/conf/SCORPION has been copied to:

http://scorpion.sorbs.net/SCORPION

/etc/make.conf contains 'KERNCONF=SCORPION'

then I follow the instructions in the Makefile....

cd /usr/src
make buildworld
make buildkernel
make installkernel
reboot
mergemaster -p
make installworld
mergemaster
reboot

Nothing that I can see I'm doing wrong....

(before I read the man page for make.conf I was using KERNCONF=SCORPION 
in the appropriate places on the command line)
