[CentOS-devel] anaconda dependency calculation?

Thanks for the info, i'll keep eye on that list to see what you 
discover. I used genhdlist as per v4.x which worked fine with a few 
tweaks. I've now got a pretty solid respin.

However i came across the redhat buildsys list 
(https://www.redhat.com/archives/fedora-buildsys-list/)  which i didn't 
know about until recently and then discovered Pungi on it 
(https://hosted.fedoraproject.org/projects/pungi) for Fedora which looks 
very promising.

I'm going to have a go at getting it to work for CentOS 5 at some point, 
as really there shouldn't be too much in the way of differences and it 
purports to do full dependency resolution.

Cheers
Nick

always get told off about :)
