That is nice and I did not notice it, still I find it useful to
download as many as possible rpms before hand and leave big remaining
for later .. when I am back at my working place (with high bandwidth)
- same behaviour as F10 had.

would like yum to solve it rather then me figuring out which package
requires which package and doing yum --downloadonly install for each.
