Gentoo Catalyst LiveCD Builder
I just found a means to create your own Gentoo LiveCDs. Since I'm finally getting around to building my router, and retiring the pentium 133 that has served us so well these past 4 years, I thought that the replacement should have zero moving parts.
Consequently I've spec'd the system with an 866Mhz Pentium III CPU, although I was torn between the Intel PIII and the Via C3 Nehemiah 1Ghz, 256 MB PC133 ECC RAM, a fanless Zalman CNPS6000-Cu, see below, and a Compact Flash to IDE adapter for a 128MB CF read only file system.
I'm really impressed with the great maintainability inherent in Gentoo, and so I was planning on using Gentoo as a base for the router OS.
Catalyst is the tool that you'd use to build a Gentoo LiveCD, which is what my CF filesystem will be effectively, the info about Catalyst is here:
Here's a more in depth howto covering the entire process:
