Digging around the preceding code this looks actually more like a thing for AIX and similar systems;
I would now expect that DI_MOUNT_FILE should be defined through one of the other options above –
if there is even an equivalent to /etc/mnttab on macOS. But the actual error comes from a function
trying to read from DI_MOUNT_FILE below, so may still be related.
