> Want to have security updates? That depends. If the security update is for a local vulnerability on my own single-user workstation then I may think twice before installing it. In other words, if the security risk is minimal then it may not be worth the hassle of upgrading my kernel and having to recompile custom drivers and programs. I spent a lot of time tweaking my system to get it set up the way I like, and I don't completely trust yum not to screw things up. For example, why not just disable the older kernel instead of deleting it: --> Populating transaction set with selected packages. Please wait. ---> Package kernel.i686 0:2.6.18-8.1.8.el5 set to be erased
