In the following scenario, I think Interop.Unix.realpath(dotnetExeFromPath) would return "/stash/homes/myself/bin/dotnet", but info.LinkTarget would be null:

• PATH includes /home/myself/bin
• /home is a symbolic link to /stash/homes
• /stash/homes/myself/bin/dotnet is a regular file

Does that difference cause any problem?

I don't think it matters. Once we located the real dotnet executable, it's parent path can be considered a "dotnet root". Whether that parent path contains links shouldn't matter: the SDK only uses the path for finding stuff beneath it, it doesn't care about the path itself.
