5.5.3.1. ...downloading but not installing updates?
By enabling the do_download and do_download_deps options, you can configure yum-updatesd to download available updates and related dependencies without installing them. This enables you to review the list of updates using Pup and then install selected updates without further download delay.
To set this up, configure /etc/yum/yum-updatesd.conf with these options:
# automatically install updates
do_update = no
# automatically download updates
do_download = yes
# automatically download deps of updates
do_download_deps = yes
