Kexec is a feature that allows to boot kernels from a working kernel. It was originally intended for use by kernel and system developers who had to reboot several times a day. Soon, system administrators for high-availability servers found use for it as well. As systems get more and more advanced, and boot times get longer, end users can now benefit from it.

I knew we'd get one or two people wading in with 'OpenSolaris does this, Linux is just copying!' I'm also not too interested in what has been available internally either, as it kind of negates the word open. But I digress.

Yeah, it's really a shame that Sun's not just throwing shit against a wall and looks what sticks, like the Linux folks do, and prefers for things to be designed and work stable enough out of the box... >_>

And since we're on topic, regarding your highlighting bullshit, I'm certain various BigCo's related to Linux kernel development are holding back a lot of code until stabilization, too. So don't give us that "Hurrrrrr, OpenSolaris!" bullshit. Then again, why am I arguing with YOU? It's like talking to a wall.

Unfortunately, Kexec was committed around about 2002/2003. It's mainly been used by kernel testers over the years because it makes things far easier, but it's been used by many for a while to get new kernels and updates running on their servers and it's gained more attention in these times of 'instant-on' access.

So what? Sure wasn't being used much or promoted outside kernel testing.

Cry me a river. It's the same sad line of 'stable' and 'out-of-the-box' reasoning I have had from every Sun consultant for the past ten years as I have yawned at him even after they've had their lunch eaten year after year.

Throwing shit at a wall, as you so eloquently put it, and seeing what sticks and then refining it in a Darwinian sense is the mark of having an open source community. Let me know when people are doing that with Solaris without the benevolent leader telling us what is stable and mission critical(tm) ;-).

Who knows? Maybe Kexec is the wrong universal approach and people should just concentrate on making hardware Linux boot faster?

And since we're on topic

Well, no, we never were. We simply got some smart Alec coming in telling us that Solaris did this first - when it hasn't ;-).

regarding your highlighting bullshit, I'm certain various BigCo's related to Linux kernel development are holding back a lot of code until stabilization, too.

Errrrr, nope. Unless you commit early and release often you quite often get left behind in the Linux world, or your code simply gets rejected with all your effort wasted. You might have something in a personal Git repository for a few weeks, but you can't sit on it for months or years until it is past by IBM or Red Hat marketing ;-).

So don't give us that "Hurrrrrr, OpenSolaris!" bullshit. Then again, why am I arguing with YOU? It's like talking to a wall.

I'm sorry. I made an assumption about what the word open was actually supposed to mean there. Quite clearly it means something different in OpenSolaris.

So what? Sure wasn't being used much or promoted outside kernel testing.

I'm afraid that your original point, like a bull in a China shop, was that Solaris had somehow done all this first and Linux was copying. I hate to burst your bubble, but there it is.
