Linux kernel updates without reboot

Here’s another great reason to use Linux over Windows.    Ksplice Uptrack provides for runtime patching of the Linux kernel without rebooting of the machine.  This has great advantages where you need to maintain the security of a server but have limited opportunites to reboot due to SLA’s (Service Level Agreements).   Ubuntu Linux was the first supported operating system, other variants are now available too, though often for a fee.
