Description Carlos 2021-11-16 19:55:15 UTC

Description of problem:

The service opensmtpd won't start with message:

opensmtpd.service: Failed to set up mount namespacing: No such file or directory

Version-Release number of selected component (if applicable):

OS: Rocky 8.5

OpenSMTPD: 6.8.0p2-2

How reproducible:

Always in the latest version (6.8.0p2-2).

Works in previous version (6.8.0p2-1).

Steps to Reproduce:

1. Install OpenSMTPD

dnf -y install epel-release && dnf -y install opensmtpd

2. Try to start the service

systemctl start opensmtpd.service

Actual results:

The service fails to start with the meessage:

Job for opensmtpd.service failed because the control process exited with error code.
See "systemctl status opensmtpd.service" and "journalctl -xe" for details.

And from journalctl:

nov 16 08:36:03 myhost.example.com systemd[1]: Starting OpenSMTPD mail daemon...
nov 16 08:36:03 myhost.example.com systemd[1821]: opensmtpd.service: Failed to set up mount namespacing: No such file or directory
nov 16 08:36:03 myhost.example.com systemd[1821]: opensmtpd.service: Failed at step NAMESPACE spawning /usr/sbin/smtpd: No such file or directory
nov 16 08:36:03 myhost.example.com systemd[1]: opensmtpd.service: Control process exited, code=exited status=226
nov 16 08:36:03 myhost.example.com systemd[1]: opensmtpd.service: Failed with result 'exit-code'.
nov 16 08:36:03 myhost.example.com systemd[1]: Failed to start OpenSMTPD mail daemon.

Expected results:

The service should start successfully .

Additional info:

A little investigation tells me is related to the last release. From changelog:

**2021-11-05** - Denis Fateyev <denis> - 6.8.0p2-2
- Add hardened security settings to service
- Set "mbox" delivery method usage by default

**2021-01-20** - Denis Fateyev <denis> - 6.8.0p2-1
- Update to 6.8.0p2 release

I think this is the change to blame:
https://src.fedoraproject.org/rpms/opensmtpd/c/92611f2d37da8518783451cfb9f749f42a3b97c4?branch=epel8

I can confirm that previous version (6.8.0p2-1) is working as expected.

dnf install -y https://kojipkgs.fedoraproject.org//packages/opensmtpd/6.8.0p2/1.el8/x86_64/opensmtpd-6.8.0p2-1.el8.x86_64.rpm

systemctl start opensmtpd.service

systemctl is-active opensmtpd.service
active
