I also discovered why the filesystem was filling up so quickly. I didn't read the docs or the dmsquash-live-root.sh script closely enough. There's a line where a 512MB snapshot overlay is created if you don't specify your own overlay filesystem[1] There's another thread from way back in 2009 where the overlay file is discussed along with the lack of a stackable filesystem (AUFS, unionfs, or similar)[2]. Are there any other good options for persistent data for servers booted via live boot? I'm writing some scripts now that make symlinks from certain directories back to a persistent storage volume on the host.
