FWIW, two more points: 1) yes, it's a MUST for some subsystems (BPF has this even documented); 2) there are tools (`b4`) that rely on the cover letter (shazam feature or multiplying trailers if it/they was/were given against the cover letter). > Use your common sense, if there is no documented thingy. -- With Best Regards, Andy Shevchenko
