   `CONFIG_FILE_NAME` includes `bpf_pinning`, `ematch_map`, `group`, `nl_protos`, `rt_dsfield`, `rt_protos`, `rt_realms`, `rt_scopes`, and `rt_tables`.
 
+- The `systemd.oomd` module behavior is changed as:
+
+  - Raise ManagedOOMMemoryPressureLimit from 50% to 80%. This should make systemd-oomd kill things less often, and fix issues like [this](https://pagure.io/fedora-workstation/issue/358).
+    Reference: [commit](https://src.fedoraproject.org/rpms/systemd/c/806c95e1c70af18f81d499b24cd7acfa4c36ffd6?branch=806c95e1c70af18f81d499b24cd7acfa4c36ffd6)
+
+  - Remove swap policy. This helps prevent killing processes when user's swap is small.
+
+  - Expand the memory pressure policy to system.slice, user-.slice, and all user owned slices. Reference: [commit](https://src.fedoraproject.org/rpms/systemd/c/7665e1796f915dedbf8e014f0a78f4f576d609bb)
+
+  - `systemd.oomd.enableUserServices` is renamed to `systemd.oomd.enableUserSlices`.
