Is there a way to get Kernelcare to just check and see if an update is available? Don't apply the update, just see if an update is available.
I had an issue with the latest 2.6.32-573.12.1.el6.x86_64+ update caused (or at least I suspect) a couple of servers to lock up. I went ahead and disabled auto updates on other servers, because I didn't want them locking up either (FWIW - some servers did update without any lock ups).
If I could script this to run a check and see if an update is available, then I can apply the update when I see fit - in case it does cause a server lock up.
But I don't see of any command-line options to kcarectl that just CHECKS to see if an update is available. All I see are options for "check for update and apply if necessary"
