Some distributions package Docker in a way that allows for a vast number of open file descriptors, often achieved through systemd's `LimitNOFILE=infinity` configuration. This situation leads to start- stop-daemon appearing to hang, consequently blocking the OpenRC init sequence. However, the issue is not an actual hang; rather, it attempts to close all open file descriptors, resulting in a loop with approximately one billion iterations of the close() syscall. This behavior effectively renders the footloose machine unable to boot. Mitigate this by setting the open file descriptor limit to 1 Mi in OpenRC's rc.conf.
