We would like to remove delta rpms (drpms) from our CentOS-6 and CentOS-7 repositories.
I live on fast connections both at home and work and for me I see no real advantage to delta RPMs - I've not really measured it, but it seems like my systems spend more time reconstructing the RPMs than they ever did downloading things. So it is of no consequence to *me* if they are done away with.
TBH I think the people you really need to hear from are those for whom delta RPMs are an distinct advantage - they are the ones who will be affected. So far I've only seen responses from people who don't mind if they are abandoned.
P.
