Dynamic Routes in Symlinks is not working

Describe the bug

Dynamic Routes in symlinks is not working

To Reproduce

I don't think github repos support symlink commits so this is how you can reproduce this:

In project folder:

mkdir pages/nolink
echo "export default function Post() {return <div>Works</div>}" > "pages/nolink/[id].js"
echo "export default function index() {return <div>Works</div>}" > "pages/nolink/index.js"
ln -s nolink pages/symlinktest

• http://localhost:3000/symlinktest/123 shows "404 This page could not be found."
• http://localhost:3000/symlinktest/ shows "works"
• http://localhost:3000/nolink/123 shows "works"
• http://localhost:3000/nolink/ shows "works"

Expected behavior

• http://localhost:3000/symlinktest/123 should show "works"

System information

• OS: Linux
• Version of Next.js: ^9.5.2
• Version of Node.js: v12.18.2

Additional context

I also tried this in next.config.js:

module.exports = {
    webpack: (config, { buildId, dev }) => {
      config.resolve.symlinks = false
      return config
    },
  }

index.js is for debug the error. Removing index.js did not help. This points to Dynamic Routes not supporting symlinks.

This is still an issue in v12.2.5. Very annoying limitation for a file based routing system.

Hard to believe that symlinks don't work... symlinks are a deep part of the filesystem. I guess if I went with Vercel this would be fixed.

@timneutkens I have symlinked pages and dynamic worked until 12.2.4 but it is broken since 12.2.5.

Nothing is reported as breaking change in such minor version, could you please give me some hint?

I tracked the changes as following:

• It works up to 12.2.5.canary-3
• It fails since 12.2.5.canary-4
