[SOLVED] Show message(s) before/during rpm installation

Hi,
I have an rpm in both 32bit and 64bit versions. I have the below requests from my client:
1. When a 32bit rpm is being installed on a 64bit OS (and vice versa), we must get a meaningful message instead of failed dependencies
2. When a 32bit rpm is installed, the 64bit rpm installation (and vice versa) must fail instead of replacing the files from 32bit installation (and vice versa).

For 1, I tried using a script in %pre section to display a warning message. However, the failed dependencies message appears even before that. My spec file does not explicitly add any "Requires" packages. Is there a way I can provide a warning message based on the rpm and OS architectures?

What can be done for 2?

Thanks.

First of all packages you build should have an %{_arch} tag in the RPM file name (as in "%{name}-%{version}-%{release}.%{arch}"). That way nobody can erroneously download / install the wrong package. If anyone willingly installs an i386 package on x86_64 then they deserve nothing better.
To put it simply: their error is not what you should correct.
To put it even simpler: its PEBCAK.

Anyway, the answer you probably were expecting is here: http://www.rpm.org/wiki/PackagerDocs/ArchDependencies
