IMO, you're making a mountain out of a mole hill. Don't want to do reboots "too" often (with "too often" being subjective) then don't update "too" often. Your system is up 24/7 and you are concerned about the few minutes of downtime while the rebooting is happening? Schedule the reboot while you're sleeping. You do sleep, yes? Or while you eat lunch. You must eat. You have systems providing vital services 24hrs/day to people outside of your local network and have service level agreements? Look into load balancing and/or fail-over systems so you can update one system while not affecting the service. Of course you do understand that the software provided by Linux distributions is open-source and written by a vast number of people with no central control. I mean there isn't a central authority that can demand and enforce the edict "remove the need to reboot". So, simply define your goals for how you want to maintain your system and develop your procedures to meet these goals. -- Fedora Users List - The place to go to speculate endlessly
