Upgrading from an old athlon to a new 64 bit one.

[eculp at unixmania.com]

I have just stuck the disks from an old AMD Athlon(tm)  (1333.39-MHz  
686-class CPU) into a new box with an AMD Athlon(tm) 64 Processor  
3800+ (2387.78-MHz 686-class CPU).  I am still building a daily kernel  
with the old configuration and all is well.  Of course the old  
configuration was/is i386.  Now I need to compile for 64 bit apps.  I  
have configured a slightly modified sys/amd64/conf/GENERIC kernel and  
was going to build it as a test only to find out that a simple make  
buildkernel KERNCONF=AMD doesn't find /sys/amd64/conf/AMD.  There is  
an old reference in UPDATING from 5.0 that didn't work either.

The other question is on today's make world all seems to still be  
compiled ELF 32-bit LSB executable, Intel 80386 so I am sure missing  
something very simple.

I'm actually going to update serveral machines, both Current and  
RELENG.  All of which are up to date.  Hopefully there will be no  
major problems.  I also plan to recompile all ports once I am able to  
build and install an AMD64 world and kernel.  Right now all is working  
fine with todays, sources and kernel except they are compiled for Intel.

Any other suggestions appreciated.  Maybe someone might recommend  
upgrading the RELENG boxes to CURRENT first?

Thanks,
