The filesystem sounds similar to what Homebrew for OS X does.

More appropriately, Homebrew is very similar to GoboLinux's Rootless project.

It's also worth noting GoboLinux predates Homebrew by about 7 years.

In fact, the original documentation of Homebrew described this approach as "The GoboLinux Way". (They no longer call it that, but this reference is buried somewhere in their git history.)
