I suggested she get a Macbook when she needed a laptop, and I get far fewer calls for assistance on this than on the Linux box, and will probably replace the Linux system with an iMac when the Linux hardware goes south. Fun thread. I'm a software developer with decent Linux chops going back 15 years or so. After leaving Windows, I used Linux as my main workstation for a couple of years before switching to OSX. It is simply a no-brainer. Almost everything on OSX just works, all the time, and when it doesn't, it's pretty easy to fix. Contrast that to Linux where my complex X config (multiple graphics drivers and big monitors) broke every time I did a distro upgrade, plus all the other random hardware crap that halfway worked or never worked, even after spending hours on it. I have to hack on things all day for my job, I want my tools - i.e. my workstation and OS - to Just Work. I COULD fix most stuff, but why stick myself in the eye with a fork if I don't have to? OSX has all the power of *nix, and none of the hassles; and decades of UI experience and focus from Apple make for an extremely usable and stable GUI. Linux on servers is a no brainer, Linux on the desktop is only appropriate if you (or the geek who supports your desktop) loves to hack on Desktop Linux. I will admit things are getting better all the time, and some pre-built linux desktops and laptops are pretty sweet, but still not as slick (and stable over long-term upgrades) as OSX.

[CentOS] How to simulate minimal ISO install using stage2 image file?
Hello, I'm working on a project which automates creation of EC2 AMI images. To do this, you must use a running EC2 instance to mount an image file in a chroot jail. My problem is that I want to create an AMI that looks exactly like a minimal (nothing selected) install from the CentOS ISO image, but the stage2 image [1] file is much more minimal than that. e.g., it doesn't have yum, groups, devices, networking, etc set up as you would if you had run the ISO minimal install on a real or virtual box. I can't mount the ISO directly in the chroot (as far as I know, but I could be wrong). My question is, how can I make the mounted stage2.img chroot jail look just like a minimal ISO install? I could manually create everything (which I have started), but this is a lot of work, and I'm likely to miss something that an ISO build would have (e.g. some group). Is there some other standard CentOS script I can run after mounting the stage2.img which will do everything the installer does? Can I run the installer manually with some kickstart script? Pointers to references and documentation are welcome...

This seems like a common task - are there any good tutorials which show the exact process to create an basic CentOS image in a chroot via kickstart?
