                 Key: MESOS-9737
                 URL: https://issues.apache.org/jira/browse/MESOS-9737
             Project: Mesos
          Issue Type: Improvement
          Components: containerization
            Reporter: Gilbert Song


https://github.com/apache/mesos/blob/master/3rdparty/libprocess/src/posix/subprocess.hpp#L137

Os::strerror calls during fork-exec should be avoided, otherwise potential issues are not debuggable.
Consider using fmtlib for error code conversion
