Hi,
Crossgrading looks like a huge can of worms. The wiki page seems to
imply that systemd must be installed. If I wanted systemd I would have
stayed on Debian.

I installed arch-test which says i386. I am sure an AMD cpu will run
x86 instructions but I don't see how a x86/i386 cpu will run the
instructions that AMD presumably added.

fred@ragnok:~$ lscpu
Architecture:        i686
CPU op-mode(s):      32-bit, 64-bit
This seems to say I can run 64 bit software.


Is the i386 version of Devuan only 32bit? Else how is 64 bit installed
instead? If you want 64 bit you have to install the AMD64 version which
means I have to change the MB to one that has an AMD cpu?

Who took the lid off this can of worms?
Best regards,
Fred
