Ksplice Uptrack is an update service for the Linux kernel; it automatically delivers security and reliability improvements to your machine, without the disruption of rebooting.

By using Ksplice Uptrack, your Ubuntu Desktop or Server 9.04 will become rebootless even the kernel is updated.

Generally, all Linux distributions needs a scheduled reboot once to stay up to date with important kernel security updates. RHN (or other distro vendors) provides Linux kernel security updates. You can apply kernel updates using yum command or apt-get command line options. After each upgrade you need to reboot the server.

Ksplice Inc. today officially launched its no-reboot patching service for Linux servers. The Cambridge, Mass., start-up has about 35 customers and several thousand servers using its paid Uptrack service, in which security and maintenance patches are automatically applied to Linux servers with minimal delay and no downtime, according to Chief Operating Officer Waseem Daher.

"I've put together an automatic system for applying kernel security patches to the Linux kernel without rebooting it, and I wanted to share this system with the community in case others find it useful or interesting," said Jeff Arnold, announcing ksplice.

If you use Linux, you don't reboot very often. In my case, the only time I reboot is when I upgrade a system. But suppose, just suppose you didn't have to do that. Suppose you could even make major updates and never have to reboot your system? You don't have to imagine it anymore. Ksplice delivers the goods.

Ksplice, the technology that allows Linux kernel updates without a reboot, is now free for users of the Fedora distribution
