Re: [gentoo-user] On what to base a custom live CD?

2010-11-25 Thread Helmut Jarausch
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.

Have you looked at Tiny Core Linux; 10MB, fast to boot and extensible.
