I didn't know that Crux was a Linux From Scratch based distro.  For some reason I thought it was a binary Gentoo derivative.  (Shows what I know).  One thing this thread had me do was to revisit the LFS pages.  And I noticed this...  
CLFS or Cross Linux From Scratch.  Since I have never done cross-compiling before, I think I am going to read through the project to see what I can glean.  Eventually, as I stated, I hope to try out cross-compiling my own EFIKA system.  Gentoo is still really high on my list, but CRUX has my interest and LFS/CLFS is creeping back on the radar.  I just don't want to get too distracted by new and interesting learning curves to explore from simply "getting things done".
