Thanks for the info, i'll keep eye on that list to see what you

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
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.
(Prior apologies for the long company sponsored signature line that i
always get told off about :)
