We need inline gemfiles to not load `fileutils`. If it does, a require of `fileutils` after a `gemfile(true)` block might cause redefinition warnings because the initial require will use "rubygems version of require", which "upgrades default gems", whereas the second require will use the default version of `fileutils`, since bundler "undoes" rubygems require monkeypatches. Similar to other default gem issues, the solution is a mix of: * Lazily loading `fileutils` as much as possible. * Vendor `tmpdir` inside `bundler`. Since `tmpdir` loads `fileutils` internally, by vendoring it we can change this require to instead use bundler's vendored version of fileutils, which is namespaced so it doesn't cause any redefinition issues.
