DDJ: User Mode Linux

Following up on Dave’s “weird”ness theme of the last couple of days, here’s something from Dr. Dobb’s Journal that I think is weird – A Linux filesystem in a SQL database???:

Dike is currently working on extending the virtual filesystem—hostfs—to allow remote mounting of directories without root permissions on either end. He wants to be able to make non-filesystems on the host look like filesystems on the virtual machine. “As a proof of concept, I’m thinking about dumping a filesystem into a SQL database and booting the virtual machine off the database,” he says. “This might be nothing but a cute trick, but it would have the side-effect of allowing a user inside the virtual machine to do SQL queries on the filesystem to do instantly what would take a long time with utilities like find.”
