Linux Supports More Devices Than Any Other OS
Linux Blog recommends an interview up on the O'Reilly site with Greg Kroah-Hartman, long-time Linux kernel hacker and the current Linux kernel maintainer for the USB driver core. He updates the free Linux driver program announced almost two years ago, which has really caught traction now with more than 300 developers volunteering. The interviewer begins by asking about Kroah-Hartman's claim that the Linux kernel now supports more devices than any other operating system ever has. "[One factor is] the ease of writing drivers; Linux drivers are at normally one-third smaller than Windows drivers or other operating system drivers. We have all the examples there, so it's trivial to write a new one if you have new hardware, usually because you can copy the code and go. We maintain them... forever, so the old ones don't disappear and we run on every single processor out there. I mean Linux is 80% of the world's top 500 super computers right now and we're also the number one embedded operating system today. We've got both sides of the market because it's — yeah it's pretty amazing. I don't know why, but we're doing something right."
That's why there's OpenBSD - nothing compares, really. I still use Linux for some things, but wireless, security, innovation, documentation, etc. Linux just doesn't come anywhere near as close to OpenBSD.
So what do you do when you buy a new printer that Linux doesn't support yet? Update your ENTIRE KERNEL instead of just installing a simple driver? Repatch the changes by hand against your current kernel?
