Are you sure it's that similar?  The original poster claimed the
application started when envoked manually, but not from rc, although it
was definitely envoked from rc -- a very unusual symptom.

I meant just envoking the script: /etc/init.d/mythbackend start

Actually, the same environment as the rc scripts.  So in fact the
method I outlined will not distinguish between environment problems
and ordering if the former is the issue; you would have to use su - to
get that right.  Note that an environment problem is quite unlikely,
especially if you are using a different application.

Anyway this sulogin stuff is a bit nasty, although it could save you
from some reboots.  You can just put the script last in the runlevel,
reboot, and then carry on from there.
