Given the history of ksplice, and my innate paranoia, I don't have a pole long enough to reach it. You shouldn't either. I have a mental picture of the keys to whatever merchandising operation you may be involved in, hanging on a nail beside the front door. If something is patched and a reboot is needed to make it 100% functional, and you can't stand the thought of 2 minutes downtime while its rebooting, its time to mirror your app to a second machine and configure an automatic failover. There are some OS's that can do that, QNX comes to mind, but they aren't free. Even the QNX microkernel has a dead time of 15 or 20 seconds for a full reload of everything else. I think the applicable keyword here is TANSTAAFL. Its a universal law, and there are no shortcuts around it. IOW, if you think the lunch is free, check the price of the beer. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
