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

Hi all, I installed 64-bit arch on a low memory laptop (1G) not thinking about the higher memory requirement. Now I wonder, whether I can approach to change it by changing the pacman.conf entry Architecture = auto to Architecture = i686 and reinstall all explicitly installed packages. I feel like it should work. Any "don't do that"s, "go for it"s, "I did it"s out there :o)). -- Friedrich
