Fuse-3.10.5

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-11.0 platform.

Package Information

Fuse Dependencies

Optional

Doxygen-1.9.2 (to rebuild the API documentation) and pytest (required for tests)

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/fuse

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]

Character devices in user space should be enabled too for running the tests:

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

Installation of Fuse

Install Fuse by running the following commands:

sed -i '/^udev/,$ s/^/#/' util/meson.build &&

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release .. &&
ninja

The API documentation is included in the package, but if you have Doxygen-1.9.2 installed and wish to rebuild it, issue:

pushd .. &&
  doxygen doc/Doxyfile &&
popd

To test the results, run (as the root user):

python3 -m pytest test/

The pytest Python module is required for the tests.

Now, as the root user:

ninja install                                             &&

chmod u+s /usr/bin/fusermount3                &&

install -v -m755 -d /usr/share/doc/fuse-3.10.5      &&
install -v -m644    ../doc/{README.NFS,kernel.txt} \
                    /usr/share/doc/fuse-3.10.5      &&
cp -Rv ../doc/html  /usr/share/doc/fuse-3.10.5

Command Explanations

sed ... util/meson.build: This command disables the installation of a boot script and udev rule that are not needed.

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

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.
