[CentOS-devel] anaconda dependency calculation?

For those on this list, I found an upgrade to yum 3.1.6 and yum-utils 
1.1.2 and a few bug fixes did the trick.

I looked at pungi, but found that 1) it needs absolutely bleeding edge yum 
to run and 2) I'm totally appalled the you still need to run it as root, 
because it runs the old anaconda-runtime stuff.

I'd recommend that you stick to yumdownloader. I'd also suggest that you 
customise anaconda (if required) simply by providing an images/updates.img 
file, built with mksquashfs. No need for the arcanery of RedHat's stuff.

One thing to bear in mind is that there are a few places where anaconda 
will add packages to your transaction set based on configuration choices 
you have made. I doubt that would explain the magnitude of difference you 
saw.
