That is a completely different set of requirements than what was given by
KB.

a) Security updates would require that a yum plugin is installed to parse
that information.
b) Correct. It probably would go in /etc/profile.d or some such thing.
c) The yum is to be run by a cron job to meet KB's requirement that yum is
not run every time someone logs in. The login profile fires up if the shell
is interactive and the environment variable to not show it again is not set.
d) The GNOME/KDE gui uses packagekit to basically do a repoquery update
every couple of minutes. .  it is also a bunch of packages that a remote vm
probably won't have installed.
