This doesn't answer the question. "Don't mess up with the installation" is one thing, "read-only file system" (like on live CD) is completely different one. It looks like you don't see this very important difference. >>> What about >>> the countless Linux live-usb distributions around? Are they all going >>> in the wrong directions?

"Without committing to a permanent installation" makes no sense at all unless we're discussing burning NetBSD into PROM. "Without committing to installation to internal HDD" is completely different thing. Using a system that is installed to USB-attached storage, be it pen drive or external HDD, or installed to SD or CF card (perhaps used via USB card reader) satisfies this requirement perfectly. -- HE CE3OH...
