Hi,

the mainboard on my main workbox needs a replacement (currently still an
athlon-xp based system). So I will go amd64 with that machine. Booting
a 64bit kernel on all the 32bit binaries works fine. What gives me a bit
of a headache is how to switch?

Thought a: create a directory /64 install everything there and then switch
lib, bin /usr

Thought b: create tbz2 of all the packages and then in one run replace
the 32 packages using emerge but i might run into library problems.

Anybody has a good and efficient idea, how to do this?

Regards,

Konstantin

a sounds good. b not. b is so much work that it would be faster to do a clean
new install. In fact, I recommend a clean new install - removes a lot of
cruft. You can backup /etc - that saves you from some setup trouble.

I did this way back. I think there was some good instructions somewhere
but I can't seem to find them.

IIRC it involved doing something like an install. You boot from a CD,
install the stage tbz. Set your profile properly, and then do "emerge -ev
system; emerge -ev world".
