Make polycubed a system service #25
Description
It is not possible to run two instances of polycubed on the same system, when a second instance is launched, it closes with the following message error:
terminate called after throwing an instance of 'std::runtime_error'
what(): epoll_ctl(epoll_fd, EPOLL_CTL_ADD, fd, &ev): Bad file descriptor
Aborted
That message is not clear enough to recognize the source of the problem.
A mechanism to check if another instance is running would allow printing a more useful message, as:
Another instance of polycubed is running PID: ....
