Adding a file volume by name then moving and recreating file on host

[adam-kiss-sg]

I use podman 3.4.4 (latest version on ubuntu 22), to run a rootless container that ships syslog logs to grafana. The syslog file is mounted to the container with -v /var/log:/var/log:ro --group-add keep-groups.

When the syslog file is rotated on the host, the volume mount keeps pointing to the renamed file, eg:

On the host, after rotation there are two files:

• /var/log/syslog
• /var/log/syslog.1

Inside the container, there is /var/log/syslog, but it actually shows the content of /var/log/syslog.1 on the host.

Is there any way to mount the file in a way, that it updates when the file is moved and recreated?
