title: How would you build a database filesystem (DBFS)?
body: <p>A database file system is a file system that is a database instead of a hierarchy.  Not too complex an idea initially but I thought I'd ask if anyone has thought about how they might do something like this?  What are the issues that a simple plan is likely to miss?  My first guess at an implementation would be something like a filesystem to for a Linux platform (probably atop an existing file system) but I really don't know much about how that would be started.  Its a passing thought that I doubt I'd ever follow through on but I'm hoping to at least satisfy my curiosity.</p>
