Yum base installation to loopback file

[nstoddar]

I'm jumping through hoops trying to create a base installation of Fedora into a loopback file, for use on Amazon's elastic cloud. However, yum is giving me a lot of errors when I try to do a groupinstall of 'Base' into the mounted loopback file.

I think the problem has to do with the fact that my 'regular' OS is the x86_64 distribution, but I'm trying to install the i386/i686 distribution into the mounted loopback file/filesystem using the installroot option to yum. Can somebody verify this for me?

The error that yum gives me is this:

My yum configuration file is this:

[main] 
cachedir=/var/cache/yum-loop 
debuglevel=2 
logfile=/var/log/yum-loop.log 
exclude=*-debuginfo 
gpgcheck=0 
obsoletes=1 
reposdir=/dev/null 

[base] 
name=Fedora Core 12 - i386 - Base 
mirrorlist=htttp://mirrors.fedoraproject.org/mirrorlist?repo=fedora-12&arch=i386 
enabled=1 

[updates-released] 
name=Fedora Core 12 - i386 - Released Updates 
mirrorlist=htttp://mirrors.fedoraproject.org/mirrorlist?repo=updates-released-f12&arch=i386 
enabled=1

So, as far as I can tell, yum shouldn't know anything about x86_64 packages, but for some reason does and insists on 'upgrading' some of them instead of just installing the 'Base' group into the installroot.

Am I on the right path here? I really need to get this figured out. Worst case scenario is I have to strap in an extra hard drive and do another installation of Fedora that's just i686, so that I can do another installation of 'Base' into the installroot of the same base architecture.

NOTE: ignore the htttp part of the URLs -- the forum won't let me give actual URLs until I've posted more. It's really correct in the configuration file I'm using. Thanks.

I'm not well familiar with Fedora, although I did use for some time in the past. However, I am sure your post would be a little more helpful if you also told the forum the exact command line you are using.
