Many other deficiencies with the BSD daemon() function are documented in systemd's daemon(7) manpage.
Michael, thank you for reference to daemon(7) manpage, this is exactly that I am looking for. I will try to ask nginx developers for implementing changes required by systemd from SysV Daemons.
I would suggest ignoring some other commenters suggestions that PID files are unnecessary with systemd. Indeed, there's even a TODO item for a Type=pid-file service that would, presumably, allow even non-forking services to signal readiness by writing a PID file. I would find something like that very useful.
From TODO file "ExecRestartPre=" feature will be very useful for protecting users which edit nginx or httpd configuration files and restarts nginx or httpd to apply changes. If someone make error in configuration file and restart service - nginx or httpd will not start after stop and service will be not working. "ExecRestartPre=" feature will help to protect from such situations: https://lists.freedesktop.org/archives/systemd-devel/2014-July/021642.html Record in TODO file exists, even issue on github exists: https://github.com/systemd/systemd/issues/2175 with comment from nginx.org packages maintainer Konstantin Pavlov: https://github.com/systemd/systemd/issues/2175#issuecomment-343481962 But as I understand, feature "ExecRestartPre=" will not be included in the upcoming CentOS 8 / RHEL 8 system, because nobody of systemd developers have time to implement this feature. Or anybody of systemd developers has time to implement this feature? -- Best regards, Gena _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
