  • Defaults to true.

In theory, this flag should not be exposed to the end user. It is a low-level FUSE flag which indicates whether or not the kernel can send certain kinds of messages to it for the purposes of using it with NFS. mergerfs does support these messages but due to bugs and quirks found in the kernel and mergerfs this option is provided just in case it is needed for debugging.

Given that this flag is set when the FUSE connection is first initiated it is not possible to change during run time.
