Beyond Linux® From Scratch - Version 7.8

Chapter 5. File Systems and Disk Management

Fuse-2.9.4

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-7.8 platform.

Package Information

Fuse Dependencies

Optional

Doxygen-1.8.10 (to build 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

[Note]

Note

After the configure script has finished you will see a warning shown below. You can safely disregard this warning. 

configure: WARNING:
******************************************************************
* Please install util-linux version 2.18 or later which supports *
* --fake and --no-canonicalize options in mount and umount       *
******************************************************************

Install Fuse by running the following commands: 

./configure --prefix=/usr --disable-static INIT_D_PATH=/tmp/init.d &&
make

If you have Doxygen-1.8.10 installed and wish to build the API documentation, issue doxygen doc/Doxyfile.

This package does not come with a test suite.

Now, as the root user: 

make install &&

mv -v   /usr/lib/libfuse.so.* /lib &&
ln -sfv ../../lib/libfuse.so.2.9.4 /usr/lib/libfuse.so &&
rm -rf  /tmp/init.d &&

install -v -m755 -d /usr/share/doc/fuse-2.9.4 &&
install -v -m644    doc/{how-fuse-works,kernel.txt} \
                    /usr/share/doc/fuse-2.9.4

If you built the API documentation, install it as the root user by issuing the following commands: 

install -v -m755 -d /usr/share/doc/fuse-2.9.4/api &&
install -v -m644    doc/html/* \
                    /usr/share/doc/fuse-2.9.4/api

Command Explanations

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

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

mv -v /usr/lib/libfuse.so.* /lib: This moves the FUSE library to the root filesystem so that it is available early in the boot process in case /usr is mounted on a separate partition and ntfs-3g-2015.3.14 is built with a system-installed version of FUSE.

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.
