Why should OpenRC and Upstart adapt to a format that is not standardized
in _any_ way? The format specification should be written by Debian
people (including downstream), and be a common denominator for all init
systems wanting to be compatible. The proposal could be based on the LSB
headers, and a good extension to that has recently been proposed by the
sysvinit maintainer: Two line init.d scripts
https://lists.debian.org/debian-devel/2014/02/msg00106.html

Additionally a very good proposal for a PID 1 program was in
http://ewontfix.com/14/ "Broken by design: systemd", copied here for
convenience:

#define _XOPEN_SOURCE 700
#include <signal.h>
#include <unistd.h>

int main()
{
    sigset_t set;
    int status;

    if (getpid() != 1) return 1;

    sigfillset(&set);
    sigprocmask(SIG_BLOCK, &set, 0);

    if (fork()) for (;;) wait(&status);

    sigprocmask(SIG_UNBLOCK, &set, 0);

    setsid();
    setpgid(0, 0);
    return execve("/etc/rc", (char *[]){ "rc", 0 }, (char *[]){ 0 });
}
