600+ duplicate or duplicated firmware files exist.

[wontfix]

Over 600 duplicate or duplicated firmware files exist. Less than two years ago it was 650~MB on disk. Three years ago it was 500~MB. Today it hovers around 900MB

[Juerg Haefliger (juergh)]

Current /lib/firmware disk usage for different series:
326M bionic
695M focal
914M jammy
879M lunar

After replacing duplicates with symlinks:
309M bionic
663M focal
878M jammy
843M lunar

Even for Bionic we can shave off almost 20MB, so nominating for all series.
