Title: Can TinyCore be self-hosting?

That is, can TC be compiled *without* using things like bash, coreutils etc etc and rely solely upon busybox/ash itself?

Sure libraries are one thing, but wondering if/how to use the existing tc environment to compile itself upon?

Easy - hard ??  I honestly don't know since I don't have any programmer chops.  Just wondering, not trying to start a flamewar. :)

Nope. The Linux kernel requires bash and perl and bc and probably a few others busybox doesn't do.

to PDP-8: just for fun/learning, you could have a look at http://landley.net/toybox/about.html
"Toybox aims to provide one quarter of a theoretical "minimal native development environment", which is the simplest Linux system capable of rebuilding itself from source code and then building Linux From Scratch.."

part of the reason for the compiletc meta-extension is that the busybox equivalents work 95% of the time when compiling a toolchain, but often fail in non-obvious ways the other 5% of the time
