I couldn't think of any case, but it's a possibility. Maybe this new support could be added to FiboSandbox but keep Compile working with unionfs the same way as it does now (and switch UnionSandbox behavior to use mapped mounts later)? One problem implementing this idea is that the use of Union vs Fibo is transparent to Compile now, AFAIK. OTOH, maybe I'm just being too paranoid. -- Hisham _______________________________________________ gobolinux-devel mailing list gobolinux-devel@lists.gobolinux.org http://lists.gobolinux.org/mailman/listinfo/gobolinux-devel
