mount --bind. The permissions of the mirrored
directory can be altered in various ways.

- 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.

Bindfs comes with a (somewhat brittle and messy) test suite. Some tests must be run as root, and some tests only work as non-root.
You can run run the tests with
It requires Ruby and
sudo, and it uses
valgrind if installed.
Vagrant test runner
There is also a set of Vagrant configs for running the test suite on a variety
of systems. Run them with
--help for extra options).
You can destroy all bindfs Vagrant machines (but not the downloaded images)
