libnbd and fuse: missing /dev/fuse device

[Autumn Jolitz]

Hi Aaron,

That module does not exist in my kernel (v6.4.2.23.ga71cb-RELEASE, X86_64_GENERIC).

Would I need to add ``options                FUSE                    # Fuse support`` to the config? The option looked like it was linked to a “does nothing” entry.

Perhaps I am using a kernel that is too old? Do I need to switch to the master branch for the fuse support?
