I have been using live-helper to build the images that I've been using. The images work well in either livecd or pxe environment. They are also able to be used on removable usb drives, but I haven't tested that yet. I've had to remove a few parts of /etc/master, which weren't needed, since it's running on a more complete system, instead of a busybox system. The image sizes are a bit larger than the linuxboot images from unattended, but not by too much. The time required to create an image is drastically reduced, especially since you don't have to compile anything. I haven't used dosemu with those images, preferring to use the nt5x-install script. From what I understand, dosemu needs to be patched, so the distro versions probably wouldn't work anyway. The udhcpc-script doesn't need to be included, as it depends on busybox, and the live system takes care of that for you. That's about all that I can remember right now. I've been using this method since the end of last year, and I haven't had any problems. -- Thanks: Joseph Rawson
