Thank you. I downloaded it and tried it. Sure is tiny! Seemed to work 
fine. (unlike "a-linux" which hung on me the last time I tried it, IIRC)

Always a "possibility"! I'm gradually acquiring a few assembly skills... 
but I'm not sure what "init" is supposed to do. Quite a difference 
between the asmutils "init" and /sbin/init on my system!!! The "init" 
you're using comes from Busybox, right?

Hmmm. It seems to work okay for me - that's launching it from my "usual" 
shell or from the shell from Busybox (I guess) that I get after booting 
your disk... and mounting the partition with asmutils on it - not "from 
scratch". How would I see this segfault?

I'd be willing to attempt to modify the asmutils "init", if I knew what 
it needed to do differently. Anyone know where I can find a "newbie's 
quickstart guide to init"? Maybe I should look at the Busybox  code...

That's not much of a "suggestion". I just wanted to give ya some 
encouragement. It "should" be a "possibility" to fix any problems you're 
having with asmutils.

Best,
