[K12OSN] updates

[Will Hatch]

Hi All,

My k12ltsp (4.0.1) is working very well after an entire summer of slaving over a computer trying to figure it out.  Now, I point my mouse at the red exclamation point on my desktop and it tells me I have 75 updates!  I tried to do some a few weeks back; downloaded a critical kernal update.  I noticed when the server is rebooted, it has the old and new version of the OS.  What is the real deal with updates; which ones do I really need, can I avoid the updates for programs that I'm not even  familiar with?  Also, if I download a kernal update, am I essentially downloading another OS to my server HD, taking up storage room?  Things are running so well that I hate to mess  them up.  If someone has the time, what is the bottom line with doing updates for Fedora Core 1/k12ltsp 4.0.1?  Thanks!
