+echo "Remove stale 99-omarchy-nofile.conf systemd drop-ins"
+
+# Earlier Omarchy shipped 99-omarchy-nofile.conf using the key
+# 'DefaultLimitNOFILESoft', which is not a valid systemd manager setting.
+# systemd rejects it at manager load on every boot:
+#   /etc/systemd/system.conf.d/99-omarchy-nofile.conf: Unknown key
+#   'DefaultLimitNOFILESoft' in section [Manager], ignoring.
+# It was replaced by 20-omarchy-nofile.conf (DefaultLimitNOFILE=soft:hard),
+# but the orphaned 99- files are unowned by any package and linger on
+# upgraded systems, spamming the journal on every boot. Remove them; the
+# 20-omarchy-nofile.conf drop-in already sets the limit correctly.
