Because the existing yum-cron did it that way, I followed the model of
having the actions run corresponding yum scripts. The question is: is there
any real advantage in doing that? Why not just run "yum upgrade" and "yum
clean packages expire-cache"?
If there is a current or future advantage in using yum shell, the above
suggestion runs into an issue: "yum check-update" actually returns a value
which the calling script can use (100, if updates are pending), whereas
running check-updates from yum shell does not appear to. Is there a
solution? Should there be?
And, similarly, plugins like download-updates add command-line options, but
do not appear to add anything to yum shell. How should that be handled?
