    摘要: How to reconfigure a general purpose operating system (GPOS) into an embedded
    operating system has attracted attention for application-specific domains. Linux is currently
    one of the popular candidates for GPOSs. Although Linux has tools for kernel reconfiguration
    by letting users add or remove desired function modules, the best schemes
    of reconfiguring Linux according to a specific embedded system are not practical. Even
    after this configuration, the target Linux might still be a GPOS. In this article, we will
    propose an approach to customizing an application-specific Linux operation system.
    This approach derives from a “call graph” based on reengineering. By analyzing a
    graph-structure representation of the target system, its hardware and software specifications
    are determined. Thus, we can find the rules for removing the redundant code in
    Linux. Moreover, we employ the call graph approach to verify the system integrity at the
    source-code level. In order to demonstrate the proposed idea, an experimental system
    will also be reported in this article. The results show that our approach can significantly
    remove about 17 percent of the Linux kernel’s footprint with respect to unreachable
