Hi,

I've been happily deploying my container services in podman using podman-generate-systemd unit files. Recently I noticed a scary warning in journald:

XXX systemd[1]: /etc/systemd/system/container-xxx.service:21: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.

This KillMode line was generated by Podman.

I don't have any reason to believe that KillMode=none isn't as expected. Podman and systemd are tracking and killing my container processes correctly as far as I can tell. But the final sentence made me wonder if my unit files will suddenly stop working after a future version of systemd removes support for KillMode=none.

A quick Google search and scan of Podman Github issues didn't turn up anything related so I thought I'd ask this group.

Thanks,

brian
