WIP LD_PRELOAD library for working with the sandstorm-filesystem protocol.

The idea is that to allow programs to access a capnp filesystem simply by accessing /sandstorm-magic; the library will intercept calls to the relevant libc functions and redirect filesystem operations in this path to a server offering the filesystem protocol.

Building

Make sure you have capnproto installed on the system, check out the sandstorm source code somewhere and from the root of this repo run:

git submodule init
git submodule update
export SANDSTORM_PATH=/path/to/sandstorm/repo
make

This will generate sandstorm-preload.so

Usage

export LD_PRELOAD=/path/to/sandstorm-preload.so`
export SANDSTORM_VFS_SERVER=<address of server>
cat /sandstorm-magic/foo # or some other command
