This is fine. But if I cannot redirect stdin, stdout, stderr to different f= iles respectively. There is a `-o` option,=20 ``` -o output_file Append output from the daemonized process to output_file. If = the file does not exist, it is created with permissions 0600. ``` The problem I am having now is that daemon command was used in some freebsd rc.d scripts without the `-f` option. When I try to restart those services through python subprocess.Popen, it would hang indefinitely.=20 The problem can be easily reproduced by=20 ``` python3 -c 'import subprocess; subprocess.Popen(["/usr/sbin/service", "mytestservice", "onerestart"], stderr=3Dsubprocess.PIPE).communicate()' ``` I can add the `-f` option to fix the problem, but `-f` will override the `-= o` option, and I end up with no log at all. I think it would be nice if the daemon command can support redirecting stdi= n, stdout, stderr separately. --=20 You are receiving this mail because: You are the assignee for the bug.=
