+Subject: [PATCH 2/2] hostnamed: allow hostname change on read-only /etc
+
+The implementation of write_string_file_atomic_label() uses atomic write
+operation, which tries to create a file in /etc. Use regular file
+operation with sync flag to make sure the hostname is written to disk
+immediately.
