+Subject: [PATCH] Add Gem.default_install
+
+Most people don't install gems in the default directory, but in the
+user's directory (--user-install), this can be configured by
+distributions using /etc/gemrc, but that doesn't work for bundler since
+it doesn't read gem configurations.
+
+The default installation directory should be Gem.user_dir, not
+Gem.default_dir, but changing this invariably would break backwards
+compatibility.
+
+Instead we can add another default directory which is where gems will be
+installed to by default.
+
+Gem.default_dir is where the system gems are installed to,
+Gem.default_install is where the gems installed by the user are
+installed to.
+
+The method Gem.default_install can be overridden by distributions to
+Gem.user_dir, therefore making all installations user installations by
+default (essentially the same as --user-install).
+
+This way both bundler and gem will install gems in the same directory by
+default without users having to manually set GEM_HOME to volatile
+locations such as $HOME/.local/share/gem/ruby/3.0.0.
+
+All distributions need to do is turn this new behavior on.
+
+If a user has sudo privileges, he/she can do --no-user-install to install
+gems in the system directory (Gem.default_dir), which is the current
+default behavior.
+
+The current behavior remains unaffected: gems are still installed to
+Gem.default_dir by default.
