fakeroot

A simple crate which provides the ability to redirect filesystem calls. This crate builds a library that can be used via LD_PRELOAD.

Some examples follow.

Intercept a file: ```bash mkdir /tmp/etc echo "tee hee" > /tmp/etc/hosts FAKEROOT="/tmp" LDPRELOAD="path/to/libfakeroot.so" cat /etc/hosts

tee hee

```

Intercept a directory list: ```bash mkdir /tmp/etc echo "whatever" > /tmp/etc/🪃 FAKEROOT="/tmp" FAKEDIRS=1 LD_PRELOAD="path/to/libfakeroot.so" ls /etc

🪃

```

Options are configured via environment variables: * FAKE_ROOT: absolute path to the fake root * FAKE_DIRS: whether or not to intercept directory listing calls too * DEBUG: if set, will debug log to STDERR
