Well the "whole" point is to get the best possible software quality,
user experience and performance (accepting that we cannot maximize all
of these at the same time). It's my personal opinion that yum does
not do well on any of these three criteria.
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
