bindfs -https://bindfs.org/

bindfs is a FUSE filesystem for mirroring a directory to anotherdirectory, similarly tomount --bind. The permissions of the mirroreddirectory can be altered in various ways.

Some things bindfs can be used for:

• Making a directory read-only.
• Making all executables non-executable.
• Sharing a directory with a list of users (or groups).
• Modifying permission bits using rules with chmod-like syntax.
• Changing the permissions with which files are created.

Non-root users can use almost all features, but most interestinguse-cases needuser_allow_other to be defined in/etc/fuse.conf.

Make sure FUSE 2.6.0 or above is installed (https://github.com/libfuse/libfuse).

Download arelease or clone this repository.

Then compile and install as usual:

./configuremakemake install

If you want the mounts made by non-root users to be visible to other users,you may have to add the lineuser_allow_other to/etc/fuse.conf.

In Linux-based OSes, you may have to add your user to thefuse group.

See thebindfs --help or the man-page for instructions and examples.

The following extra options may be useful under osxfuse:

-o local,allow_other,extended_security,noappledouble

Seehttps://github.com/osxfuse/osxfuse/wiki/Mount-options for details.

Bindfs comes with a (somewhat brittle and messy) test suite.The test suite has two kinds of tests: those that have to be run as root andthose that have to be run as non-root. To run all of the tests, domake check both as root and as non-root.

The test suite requires Ruby 1.8.7+. If you're usingRVMthen you may need to uservmsudo instead of plainsudo to run the roottests.

There is also a set of Vagrant configs for running the test suite on a varietyof systems. Run them withvagrant/test.rb (add--help for extra options).

You can destroy all bindfs Vagrant machines (but not the downloaded images)withmake vagrant-clean.
