Is there a reason Unity doesn't use the Roslyn compiler by default on non-supported distros?

    Referring to unity_csc.sh in the Tools/RoslynScripts/ folder.
    I saw a massive speedup by manually enabling it for my distro, reducing compile times by 70-80%.

    Is there any downside to this or a reason why it's disabled by default?

    That is the list we know to work. If you try to run .NET Core version on a system that doesn't have required dependencies, it will simply crash and you won't even be able to open the editor.

    Can you share what enabling it means (how to do it)?
    I'd be interested in this speedup as i found compiling noticeably slower than on my windows machine.
    (And from what i gather (only?) .net core is required additionally?)

    Edit the unity_csc.sh script in the Unity/xxx/Editor/Data/Tools/RoslynScripts/
    Where "xxx" is whatever version you're using(e.g., mine is 2019.2.6f1)
    sed command to change it to always use roslyn:
    sed -i 's/USE_NETCORE=0/USE_NETCORE=1/g' unity_csc.sh

    Thanks, looking through that script it seems many 'common' distros do use roslyn already. Since i had to switch back to ubuntu i guess i won't actually need to modify it anymore then.

    Anyone tried this on Arch or Manjaro?
