You might wonder: What is the replacement? Namely, as a fallback (for
situations where the current process is running inside a container or jail):
  - On Linux, the auxiliary function get_linux_boot_time_final_fallback
    reads the info from /proc/uptime.
  - On macOS and BSD systems, we don't need to read it, because the sysctl
    invoked by the auxiliary function get_bsd_boot_time_final_fallback
    reads the same info, without needing a mounted /proc file system.
  - On Minix and Cygwin, no replacement is needed, because there is no
    "container" or "jail" concept in these OSes.
