[arch-general] Change installation from 64-bit to 32-bit

[Scott Lawrence]

Hey,

Never tried that particular piece of reckless foolery :). However, I'd guess 
that once the libraries were replaced with incompatible versions, the 
installation scripts would start to fail, and then you'd be pretty badly 
stuck.

Instead (but this requires a lot of disk space), perhaps install the 64-bit 
versions of all current packages to a chroot, and then do a massive copy? 
You'd have to be sure to get the important parts in one command on the copy, 
otherwise your binaries might start being unusuable. (Or, install busybox and 
use that to do things more carefully.)

The wiki has a couple other methods, if you don't have 15G to spare:
