🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Append engine.relabel() to the presets bind mount.
When --selinux is enabled with Podman, the model mounts receive ,z, but the presets mount does not. Podman can deny llama-server access to /etc/presets.ini.
Proposed fix
- f"--mount=type=bind,src={get_container_mount_path(presets)},destination=/etc/presets.ini,ro"
+ f"--mount=type=bind,src={get_container_mount_path(presets)},destination=/etc/presets.ini,ro{engine.relabel()}"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
