Rethinking Failsafes for Critical Linux Systems
,----[ Quote ]
| Yes! The configurations of Linux and server
| applications are often customized during the
| installation as well as ongoing maintenance and
| general troubleshooting. Even servers with very
| similar functions are often configured
| differently. A primary goal to protecting a
| critical Linux server is being able to repair or
| replace the system and get it back into
| production quickly.
|
| The best-documented changes can quickly become
| outdated and often cause errors if not found
| until the damage has been done. Having a process
| that will automatically protect the unique
| configuration information will allow those
| changes to be applied to a standby or
| replacement server for rapid recovery.

How to quadruple your productivity with an army of student interns
,----[ Quote ]
| Startup companies are always hunting for ways to
| accomplish as much as possible with what they
| have available. Last December we realized that
| we had a growing queue of important engineering
| projects outside of our core technology that our
| team didnât have the time to finish anytime
| soon. To make matters worse, we wanted the
| projects completed right away, in time for our
| planned product launch in early February.

Ksplice debuts zero downtime service for Linux

No more rebooting. Period.
,----[ Quote ]
| Thereâs a new technology in town for the
| Linux operating system called Ksplice
| Uptrack. With this system in place you can
| now update your system - even the kernel -
| without a single reboot. Let me say that
| again - EVEN THE KERNEL! What exactly does
| that mean? You know all of those promises
| made by other OS vendors who claim a near
| 100% uptime with their machines? What
| happens to those machines when you install
| a service pack that does anything to the
| kernel? Time for a reboot (Actually it
| doesnât even require a kernel-level update
| to require a reboot.)

Linux reboots are a thing of the past with Ksplice
,----[ Quote ]
| Even though the Linux operating system is
| very stable and rarely needs a reboot,
| there are times when an update (such as a
| kernel update) will make this a
| requirement. At least that used to be the
| case. That is correct. With the help of a
| newly developed technology (dubbed Ksplice)
| even a kernel update will not require a
| reboot. This is fantastic news to
| administrators who depend upon constant
| uptime for their servers and production
| desktops/machines.

splice gives Linux users 88% of kernel updates without rebooting
,----[ Quote ]
| Have you ever wondered why some updates or installs require a reboot, and
| others donât? The main reason relates to kernel-level (core) services running
| in memory which either have been altered by the update to include new data
| that canât be âsqueezed inâ to its existing footprint, or are currently
| attached to multiple separate processes which cannot be accounted for without
| a reboot. Ksplice has figured out a way around that issue in a majority of
| the cases.
|
| [...]
|
| This technology is only for Linux at the current time. No features like this
| are available for Windows. The technology does require a kernel patch, as
| Ksplice itself must be integrated into the kernel. The installation software
| (.deb package) handles this for you.

Interview with Ksplice Co-Founder
,----[ Quote ]
| Ksplice is an amazing new technology which allows patches to be applied
| directly into a running kernel, without needing a reboot. Linux Magazine
| talks with co-founder and Chief Operating Officer and discusses the origins
| of the project and what it has to offer.

Never reboot again with Linux and Ksplice
,----[ Quote ]
| By default, Ksplice shows up in your system menu-bar so you can keep an eye
| on what's happening with your updates. While Ksplice itself is open-source
| software, and the service for individual users is free, you'll need to pay a
| service fee if you're a business using Ksplice to keep your servers
| up-to-date.
|
| Since Ksplice doesn't require any changes to the Linux kernel I strongly
| suspect you'll soon be seeing its technology used with other Linux
| distributions. After all, as great as Linux is about letting you run for
| months on end without wasting time or money on a reboot, it will be even
| better when we can run Linux for years without rebooting.

Ksplice Offers Rebootless Updates For Ubuntu Systems
,----[ Quote ]
| Ksplice has started offering Ksplice Uptrack for Ubuntu Jaunty, a free
| service that delivers rebootless versions of all the latest Ubuntu kernel
| security updates. It's currently available for both the 32 and 64-bit generic
| kernel, and they plan to add support for the virtual and server kernels by
| the end of the month, according to their FAQ. This makes Ubuntu the first OS
| that doesn't need to be rebooted for security updates. (We covered Ksplice's
| underlying technology when it was first announced a year ago.)
