Re: [gentoo-user] On what to base a custom live CD?
I'd suggest SystemRescueCD. It's upgraded quite often (currently using kernel 2.6.35-x) has a ready to go X11 environment and most useful, it's an up-to-date Gentoo system, so one immediately knows where to look if there are any problems. And it has a well documented (easy) procedure for extending it. Helmut.

It it actually booting all that time, or is it waiting for user input? I doesn't take anything like that long to boot on my netbook, but I have modified the USB install to set a keymap choice and a couple of other options. > Does anybody have an recommendations for a good way to build a small > liveCD with a custom kernel module? Have you looked at Tiny Core Linux; 10MB, fast to boot and extensible. -- Neil Bothwick Deja Foobar: A feeling of having made the same mistake before. signature.asc Description: PGP signature

Apparently, though unproven, at 00:02 on Thursday 25 November 2010, Grant Edwards did opine thusly: > I need to build a liveCD that boots on as wide a variety of hardware > as is practical.
