care

make linux programs reproducible on all linux systems

CARE monitors the execution of the specified command to create an archive that contains all the material required to re-execute it in the same context. That way, the command will be reproducible everywhere, even on Linux systems that are supposed to be not compatible with the original Linux system. CARE is typically useful to get reliable bug reports, demonstrations, artifact evaluation, tutorials, portable applications, minimal rootfs, file-system coverage, ... By design, CARE does not record events at all. Instead, it archives environment variables and accessed file-system components -- before modification -- during the so-called initial execution. Then, to reproduce this execution, the re-execute.sh script embedded into the archive restores the environment variables and relaunches the command confined into the saved file-system.
