--- Comment #8 from Fabio Valentini decathorpe@gmail.com --- Thanks for adding the file as an additional source and filing an issue upstream. However, the file is now just unused in the package. You still need to put it into the correct place and mark it as a license file:
- do something equivalent to `cp %{SOURCE1} .` at the end of the %prep scriptlet (i.e. after the %cargo_prep line) - add this line at the start of the %files list for the "devel" subpackage: `%license %{crate_instdir}/LICENSE`
