and you think performance and user experience will get better
by downloading packages for dep-solve?

are you aware that many people do not have endless bandwith,
traffic-limuts and storage and can you imagine how slow
this all would be?

yum should not waste ressources which i did even in the
recent past by consuming wy too much memory resulting
get killed from oom-killer on machines with 512 MB RAM

and yes, 512 MB RAM are really enough for many servers
and there is no argumentation for a UPDATER eating more
ressources as the whole server in normal operations
