naw, much better to put something in spec file like
livecd/linuxrc: <path to my linuxrc>

As andrew already mentioned it's a 'module' inside catalyst that
describes how to build a certain type of system from a spec file.

I actually implemented it as part of the 'kernel' arguments to the
spec file.  My files look something like this:

boot/kernel: vanilla
boot/kernel/runscript: /usr/lib/catalyst-devel/targets/embedded/kmerge.sh
boot/kernel/vanilla/sources: =sys-kernel/vanilla-sources-2.4.26
boot/kernel/vanilla/config: /root/kernel-config
boot/kernel/vanilla/gk_kernargs: --arch-override=x86 
--linuxrc=/tmp/mergeroot/linuxrc
boot/kernel/vanilla/gk_action: all

help at all ?
