Android's init would be my obvious model _except_ that it parses config  
files that look like a shell script but aren't. This tempts people to  
add shell script snippets in there, which don't work.

The openrc stuff gets patched, or busybox gets patched?

I could write a replacement for busybox init in a weekend. I actually  
_did_ back in 2005 but it got lost in a laptop crash.

Replacing the scripts is not my goal. Satisfying the use cases that led  
to upstart and android init _and_ being reasonably compatible with  
sysvinit is.

I need to sit down and study what everybody else did, to work out why  
they did it. This is a largeish project I haven't started yet because I  
have too many other open cans of worms to deal with at the moment. :)

One script is in Andrew's tree, the other is in the kbuild tree I  
think. It looks like 3.10 is when they go upstream.

I should check linux-next and see if they're in there yet...
