How to write a working rc.d script for OpenBSD to launch a ruby program that lives in /sbin/?

Question

This is everything that I've done:
I wrote the rc.d/ script, it looks like this:

#!/bin/ksh

daemon="/usr/local/sbin/dynaruby"
name="dynaruby"

. /etc/rc.d/rc.subr

rc_cmd $1

The program needs an environment variable to work. I tried setting it up following the man page of rc.d. It says to create an entry in login.conf, so I did, and that looks like this:

dynaruby:\
        :setenv=DYNARUBY_KEY="BupCxeBEflVyNK05ypuz25bXuoRc9Rg61qKnOBohyH0=,Xwsirr99KDqkz3Ncytn2AA==":\
        :tc=default:

I also did cap_mkdb /etc/login.conf for good measure, but still when I do rcctl reload/start dynaruby I always get dynaruby(failed). I tried having a file entry in /etc/login.conf.d/ without :tc=default: (tried both :tc=daemon: and nothing at all) instead of having it inside the main login.conf but with the same results. Any insight on how I could debug this further would be greatly appreciated.

EDIT: I forgot to say that I also added the service in /etc/rc.conf.local

I've managed to force the env variable into the script by overriding the default rc_start

#!/bin/ksh

daemon="/usr/local/sbin/dynaruby"

. /etc/rc.d/rc.subr 
  
 rc_start() { 
 export DYNARUBY_KEY="YOUR,KEY" 
 exec /usr/local/sbin/dynaruby & 
 } 
 rc_cmd $1

This is not the intended way to do this, but I guess it works. Without exec the program will run fine until the rc.d framework kills it with error Timeout: No process found. This might be fixed by overriding the pexp too, but I found just using exec / & to be the easiest.
