if you are only referring to nghost, if you run it with the "passive" memory mode option it'll live in about 35mb. As for the install footprint, with all its deps, you may have to run it from a usb drive, or at least put the skin on the thumb drive.I have a thin client I'm looking to use for a carPuter. Specs are 733mhz Eden/128ddr/64 flash. Will it fit or will I have to boot of a thumb drive? Is 128mb of ram enough?
for your setup, you'd definitely want a smaller OS than LinuxICE which is too generic of a solution than what your needs permit.
