Ubuntu Precise has a number of warts that made it non-trivial to add initially, but I've managed to work through some of them and come up with a working build. Two important parts to note are that it has neither the `btrfs` nor the `devicemapper` graphdriver backends since `btrfs-tools` and `libdevmapper-dev` in the precise repositories are too ancient for them to even compile.
