+   * update-linbofs: only copy currently needed firmware into linbofs (#153, 0013e2f).
+   * update-linbofs: fix undetected kernel module extraction failure (f2f9873).
+   * update-linbofs: avoid unnecessary firmware list download from kernel.org (0e51ac8).
+   * update-linbofs: speed up firmware lookup via a one-time index (8801dda).
+   * update-linbofs: bail out instead of silently building a broken linbofs on copy/setup failures (8e01bfe, 5e991cb).
+   * update-linbofs: quote variables in path expressions (c278695).
+   * update-linbofs: detect missing firmware directly from generic kernel message (#154, ab41c6e).
+   * update-linbofs: reuse cached firmware instead of re-downloading every run (7306a25).
