[systemd-devel] [systemd-nspawn] nginx: [emerg] open() "/dev/stderr" failed (6: No such device or address)

I used this setting:

  error_log /dev/stderr warn

But I must admit, I thought that this is the default of the Arch Linux
package. But they use this setting in their nginx-package:

  error_log stderr

Here's their service-unit

  [Unit]
  Description=A high performance web server and a reverse proxy server
  After=network.target
  
  [Service]
  Type=forking
  PIDFile=/run/nginx.pid
  PrivateDevices=yes
  SyslogLevel=err
  
  ExecStart=/usr/bin/nginx -g 'pid /run/nginx.pid; error_log stderr;'
  ExecReload=/usr/bin/kill -HUP $MAINPID
  KillSignal=SIGQUIT
  KillMode=mixed
  
  [Install]
  WantedBy=multi-user.target

I tried that setting in my virtual machine and it worked like a charm:

  error_log stderr warn;

Sorry for the noise. Should have used this setting from the beginning. Thanks a lot for the help.
