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

Message-Id: ick212$al8$
1 I need to build a liveCD that boots on as wide a variety of hardware
2 as is practical. It needs to load one custom kernel module and then
3 run one console-mode application. Instead of building something from
4 scratch, I was hoping I might be able to modify an existing liveCD.
6 There's no need for support for networking, graphics, or even access
7 to optical or hard drives.
9 The current version of this CD is built sort of from scrach using a
10 labor-intensive and error-prone process. However, it does produce
11 something that's small (less that 10MB), and boots fast (around 10
12 seconds). But, updating the existing CD with a newer kernel (to gain
13 support for newer hardware) is difficult.
15 I thought about using a customized systemrescuecd, but that takes ages
16 to boot (almost 5 minutes). This CD is intended as something a
17 customer can run to do a quick hardware test, and making them sit
18 there for 5 minutes to see a 5-second test just isn't going to fly.
20 I also looked at the gentoo minimal install CD, but that's still
21 pretty slow (3-4 minutes), and it's not at all obvious how to add a
22 kernel module to it.
24 Does anybody have an recommendations for a good way to build a small
25 liveCD with a custom kernel module?
