I propose to do this by adding the two functions daemon2_fork() and

Please could you show how to implement daemon() in terms of daemon2_*.

Could the args be passed to daemon2_fork() instead of to
daemon2_detach(), to make it easier to convert code from using daemon()
to daemon2_*()?

If we are redesigning this interface, then perhaps we should go further, and provide a richer list of things to do in between the fork and the detach. Some possible things one might want to do are: setuid, chroot, chdir(somewhere other than "/"), anything that posix_spawn() can do.
