Hello, I have 64 bit processor and 64 bit compatible CentOS 5.5 distribution, but some times when I run yum info, I get information about both 32 abd 64 bit installed packages:
For example when I reinstall selinux I see that previously I had both archetecture match packages version:

Reinstalling:
libselinux i386 1.33.4-5.5.el5 base
libselinux x86_64 1.33.4-5.5.el5 base

My question is: Is there some rpm or yum configurable option to strict installation to some archetecture, that, that when rpm/yum will try to install package for i386 when it prohibited I will get some error?

Thank you for ahead.

This has always been a 64-bit install, right?

If it's installing 32-bit packages, it's doing so for a reason. I would not try to stop it.

You can add the following line in the [main] section of /etc/yum.conf:

May be it do it for reason, I don't know, but I think that it may cause some problems when your system has packages of another architecture.

It works also for disable x86 updating?
I get this during updating:
Updating:
NetworkManager i386 1:0.7.0-10.el5_5.1 updates 1.0 M
NetworkManager x86_64 1:0.7.0-10.el5_5.1 updates 1.1 M

And I put exclude line here:
[main]
(some other configurations)
exclude="*.i386 *.i586 *.i686"

I haven't tested but try to remove the double quotes and do it again.

There's no problem; x86_64 processors can run i386 programs and they can coexist on your machine.

Yes, I know that both of them may coexist.
And there is no need for "" in this line. Without quotes yum realy filters the packages.
