ramdisk

[David Jones]

FYI

I just compiled the latest busybox( again ).  Created
a new ramdisk image with it.  Then build a kernel
using both.  It booted! :)  So now it's down to
testing pivot_root and a linuxrc config.  Thanks for
the info below.  With any luck I should have some good
news later this evening.
