Environment deduction is unreliable in ECS Fargate

[lightbody]

Expected Behavior

The code in question is here, it seems:

    private static boolean isEC2Linux() {
        if (readFile(EC2_LINUX_HYPERVISOR_FILE).startsWith("ec2")) {
            return true;
        } else if (readFile(EC2_LINUX_BIOS_VENDOR_FILE).toLowerCase().startsWith("amazon ec2")) {
            return true;
        }

        return false;
    }

Basically, we are finding in the real world in the last week or so this will return true or false seemingly randomly. I suspect the underlying infrastructure is getting shifted around behind the scenes.

Regardless, I would expect that in all forms of ECS the auto-detection for AMAZON_EC2 works, or a new AMAZON_ECS option is introduced that can deal with the nuances there.

@lightbody the workaround would be to disable environment deduction and configure the environments you require explicitely.
