Edward, be aware that the preceding link represents a substantially
different philosophy about init than Rich Felker's PID1 and Suckless
Init PID1. The preceding link is *not* a minimal PID1. I could argue
either philosophy (but in truth I like Felker's model). The thing I'd
say to you is that if you're writing your first init, I'd have it
*only* spawn /etc/rc and spin (and in real life listen for signals and
act on them). Writing a PID1, writing the /etc/rc and the shutdown
script, and connecting it to s6 or runit is quite enough work for a
first stab. I'd keep PID1 ultra-simple on the first stab. Later you can
make something more like the referenced link.
