   Testing kernel updates is very tedious.  The testing procedure is to   
   install the current version of the kernel from release or updates, as   
   well as things like virtualbox, that uses dkms modules, ensure it's   
   working, then install the update, checking to ensure the dkms modules   
   are built ok, reboot into the updated kernel, and check for any   
   obvious regressions.   
      
   This has to be repeated for each of the versions of the kernel shown by   
   urpmq -y latest|grep ^kernel|grep -v -e devel -e source   
      
   That's 11 kernels on i586, 9 on x86-64, where the desktop586 kernels are   
   not expected to work.   
      
   So 20 reboots ensuring the old kernels and dkms modules are working before   
   installing the updated kernels, then another 20 after installing.  All   
   of which has to be done on real hardware, not in virtualbox or similar,   
   although there is some additional testing of kernel updates under   
   virtualbox too.   
      
   Normal kernel updates are usually in qa testing for at least a week,   
   if not more. Getting that done in one day is really pushing it.   
      
   When there's a major security fix like the latest one, no other kernel   
   changes are included, in order to minimize the chances of a new   
   regression.
