Reading more closely I see it involved ditching glibc/initscripts too

 "Anyway after a little manual janitorial work I had it down to kernel+busybox.
  (note - busybox is statically linked so I dumped glibc)
  aside from the homemade inittab and rcS (init script) it was all from
  the Fedora distro,'

So pretty much only bits of Fedora in use are the kernel & busybox, even
the init scripts are custom. So not really much trace of Fedora left at
all. Not sure why you'd go to the trouble of doing the initial  anconda 
install at that point - might as well just 'rpm --no-deps' install kernel
+ busybox RPMs into a chroot & add the custom init script.
