I wander if we'd learn anything by starting /sbin/init under
strace ?

I've never tried this before, but it might be worth a try.

add "init=/linuxrc" on the command line, then create a shell
script that does "strace /sbin/init". You might have to redirect
stderr to stdout.

Dropping down an /sbin/init from Debian/RedHat/SuSE might be
interesting too.
