Hallo!

I'm trying to run my application in podman rootless container and I stumble on following problem: my program needs /proc/sys/fs/mqueue/msg_max to be at least 256, but in running container this value is just 10. When I try to specify this parameter while running the image (--sysctl 'fs.mqueue.msg_max=256') I get the following error:

Error: open /proc/sys/fs/mqueue/msg_max: Permission denied: OCI permission denied

and container is not created.

My host where container is being run has this parameter set to 256. How can I expose current host setting for msg_max to my container?

Best regards,

When you login to your user account is is et to 256? $ cat  /proc/sys/fs/mqueue/msg_max 10
