Looking for some advice on setting up ionice for the following binaries: mythbackend, mythfrontend, mythcommflag

My limited understanding of how to properly use ionice is to leverage the /user/local/bin directory, a wrapper script, and symlink.

/usr/local/bin/nicer-2.1
Code:
#! /bin/sh
ionice -c 2 -n 1 nice -n 20 /usr/bin/"${0##*/}" "$@"

symlink script to binaryName.
Code:
ln -s nicer-2.1 /user/local/bin/binaryName


ionice is only binding to the mythcommflag binary, probably due to how the other binaries are being called/referenced. I made another script for the /usr/LH/bin directory and created a link for LinHES-start seeing if that would trigger ionice on mythfrontend. The result was the LinHES-start was ioniced but mythtfrontend still ran in the default ionice class.

I used this approach as its seems the least obstructive method to preserve the LinHES environment; I am open to other delivery mechanisms (proceas id, sv, ...).
