You are running the IOC as root, so of course it won't inherit the
environment variables from your personal account:

Whatever wrapper you are using to run the IOC is replacing your personal
environment with root's (which is a good thing from a security
perspective, you don't want a user's LD_PRELOAD value to leak into a
root process for example).
