The yum-downloadonly plugin is very useful, especially in production
environment, when automatic updates is not a good idea. But using
"--downloadonly" option, the packages are stored in some "special", "too deep",
per-repo subdirectories (i.e. /var/cache/yum/core/packages/ for Core,
/var/cache/yum/extras/packages/ for Extras etc.) It is not very convenient indeed.

I propose to add "--downloaddir=DIR" option to this plugin, which allows to
store  packages in the specified place instead, i.e.:
"yum -y --downloadonly --downloaddir=/var/spool/update update"

We already use such a modified plugin for a long time (invoke yum from cron each
night).

P.S. Please, add it for FC5 too.
