 .Sh HISTORY
 The
 .Fn daemon
 function first appeared in
 .Bx 4.4 .
-.Sh CAVEATS
-Unless the
-.Fa noclose
-argument is non-zero,
-.Fn daemon
-will close the first three file descriptors and redirect them to
-.Pa /dev/null .
-Normally, these correspond to standard input, standard output, and
-standard error.
-However, if any of those file descriptors refer to something else, they
-will still be closed, resulting in incorrect behavior of the calling program.
-This can happen if any of standard input, standard output, or standard
-error have been closed before the program was run.
-Programs using
-.Fn daemon
-should therefore either call
-.Fn daemon
-before opening any files or sockets, or verify that any file
-descriptors obtained have values greater than 2.
-.Pp
-The
-.Fn daemon
-function temporarily ignores
-.Dv SIGHUP
-while calling
-.Xr setsid 2
-to prevent a parent session group leader's calls to
-.Xr fork 2
-and then
-.Xr _exit 2
-from prematurely terminating the child process.
