FC4, yumex, and security updates

I was looking at my yumex listing and I don't see a provision for getting security updates (maybe I'm missing it) but rather the kernel updates.

Do the kernel updates have the security updates in them or do I have to update them separately?

If I have to do them separately, are the updates cumulative? Can I just install the last one and get all of the protection or do I have to go back and install each one in sequence?

Thanks for your help.

Perhaps I'm missing something, but what do you mean by "security updates"? Generally, if a part of the system contains a security flaw, then that security issue will be dealt with by a subsequent release of that particular part. It will not be labelled as a security fix. If all your packages are up to date you *should* have the most secure version of everything. Updating the kernel itself sometimes causes problems though, it's usually best to leave it as is unless you have a specific reason to need to change!

Kernel related security fixes and upgrades are included in the kernel update that yum/yumex/etc offer.

Please note that once a kernel update is installed, you must reboot your machine and select (if not done by default) the newer kernel to boot from. (to change the default kernel edit as root: /etc/grub.conf, "info grub", put the cursor in Configuration and hit enter for more info)

Other packages may also have security updates and those particular packages need to be upgraded as well.

There is no need to reboot after any package update except the kernel.

Sometimes there is not even a need to reboot for kernel updates if the updates are only for particular kernel modules that can be removed temporally, updated and reloaded, but this is for more experienced users.

The good news is that Kernel updates are not too frequent, but readily available if a big security problem is found.
