I accidently installed 32 bit opensuse on several machines.
Is there an easy way to switch to 64bit? such as adding 86_64
repos and zypper --dup --allow-architecture-change
(unfortunately this option doesn't exist)?
Any hints?
A notice in the setup, that a 32bit os is going to be installed
on a 64bit system would be very nice...

:-) It might be intentional. 32bit apps use less memory, if you
a lot of them, there's more room with a 32bit os.

Would be easy to tell -- if the user has >=8G, go for 64-bit, else

Yep, not a bad idea.

Put the limit much lower:
If the system has <4G go 32bit
Not only older hardware, but also for virtual machines.

The area just above 4G could be covered with 32-bit with PAE, but that
should be considered duck-tape from the past.

Yeah, YaST already has some checks on amount of available memory, so
adding a little "Are you sure?" when someone wants to install 32bit on
a machine with 4Gb or more should be easy. Nice little opportunity for
someone to dabble with YaST development.
