In the Github issue you've linked to, they also replaced one line in a file named  `config/boot.rb`:

On my local box, there's one line to load the bootsnap/setup module, which is used to speed up Rails application loading:
```
require "bootsnap/setup" # Speed up boot time by caching expensive operations.
```

They replace that line by making the loading process depend  on your new environment variable ENABLE_BOOTSNAP:

```
require 'bootsnap/setup' if ENV.fetch("ENABLE_BOOTSNAP", "true") == "true"
```
