OSNews is Exploring the Future of Computing

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.

RE[2]: Fast Reboot

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.
