+Make sure you've followed instructions from the principal README.
+Instructions to test FUSE using the passthrough_ll example filesystem provided in the libfuse source tree:
+
+git clone git://github.com/libfuse/libfuse.git
+cd libfuse
+meson build
+cd build
+ninja
+cp example/passthrough_ll /usr/bin
+cd
+cat << 'EOF' > /sbin/mount.fuse.passthrough_ll
+#!/bin/bash
+ulimit -n 1048576
+exec /usr/bin/passthrough_ll -ofsname="$@"
+EOF
+chmod +x /sbin/mount.fuse.passthrough_ll
+mkdir -p /mnt/test /mnt/scratch /home/test/test /home/test/scratch
+
+
+Use the following config file:
+
+export TEST_DEV=passthrough_ll
+export TEST_DIR=/mnt/test
+export SCRATCH_DEV=passthrough_ll
+export SCRATCH_MNT=/mnt/scratch
+export FSTYP=fuse
+export FUSE_SUBTYP=.passthrough_ll
+export FUSE_MOUNT_OPTIONS="-osource=/home/test/scratch,allow_other,default_permissions"
