My impression from a long time ago, when it first came out on Ubuntu, was that it was essentially a kernel patch that dynamically loaded patches and provided the ability to rebootstrap a kernel that was already loaded. As it turns out, it’s a commercial product that offers the ability to not have to reboot your machine to update the kernel. Let me be frank: I’m all about that.

The part that I kind of object to is in the press release, of all things. It’s the opening line of the company profile:

Ksplice is an enterprise software company making reboots a thing of the past.

Please, lets be honest. Reboots are inevitable. Using this product as a stop-gap for untimely reboots may be handy (at the low low price of $50 per year per server), but it can’t (and shouldn’t!) replace regular reboots.

The reasons for scheduled rebooting of machines are numerous.
