Storage Execution
I'm implementing a custom filesystem on a block device supported by WiredTiger.
On startup, mongod creates the journal directory on the native filesystem (via boost in WiredTigerKVEngine constructor) instead of via the WiredTiger custom filesystem interface. This causes a failure for mongod to start with UNFS. See https://github.com/MicronSSD/unfs.
