Beyond Linux® From Scratch - Version 8.1

Chapter 5. File Systems and Disk Management

Fuse-3.1.1

Introduction to Fuse

FUSE (Filesystem in Userspace) is a simple interface for userspace programs to export a virtual filesystem to the Linux kernel. Fuse also aims to provide a secure method for non privileged users to create and mount their own filesystem implementations.

This package is known to build and work properly using an LFS-8.1 platform.

Package Information

Fuse Dependencies

Optional

Doxygen-1.8.13 (to rebuild the API documentation)

Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel if necessary: 

File systems  --->
  <*/M> FUSE (Filesystem in Userspace) support [CONFIG_FUSE_FS]

Installation of Fuse

Install Fuse by running the following commands: 

./configure --prefix=/usr    \
            --disable-static \
            --exec-prefix=/  \
            --with-pkgconfigdir=/usr/lib/pkgconfig \
            INIT_D_PATH=/tmp/init.d &&
make

The API documentation is included in the package, but if you have Doxygen-1.8.13 installed and wish to rebuild it, issue doxygen doc/Doxyfile.

This package does not come with a test suite.

Now, as the root user: 

make install                                         &&
rm -v /lib/libfuse3.{so,la}                          &&
ln -sfv ../../lib/libfuse3.so.3 /usr/lib/libfuse3.so &&

rm -rf  /tmp/init.d &&

install -v -m755 -d /usr/share/doc/fuse-3.1.1 &&
install -v -m644    doc/{README.NFS,kernel.txt} \
                    /usr/share/doc/fuse-3.1.1 &&
cp -Rv doc/html /usr/share/doc/fuse-3.1.1

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--exec-prefix=/: This parameter moves programs and libraries that could be needed before the /usr directory is mounted, to the root filesystem.

INIT_D_PATH=/tmp/init.d: This parameter installs the bootscript into /tmp/init.d as a bootscript is not required.

rm -rf /tmp/init.d: This removes the unneeded bootscript.

Configuring fuse

Config Files

Some options regarding mount policy can be set in the file /etc/fuse.conf. To install the file run the following command as the root user: 

cat > /etc/fuse.conf << "EOF"
# Set the maximum number of FUSE mounts allowed to non-root users.
# The default is 1000.
#
#mount_max = 1000

# Allow non-root users to specify the 'allow_other' or 'allow_root'
# mount options.
#
#user_allow_other
EOF

Additional information about the meaning of the configuration options are found in the man page.
