The session can't store it's data into the folder /home/vagrant/Projects/joomla-cms/installation/sessions despite the permissions is 777 from /var down to joomla-cms and also from /home down to joomla-cms on every folder.

I'm using the Joomlatools vagrant box for development. There I have the the core files in the folder /home/vagrant/Projects/joomla-cms. To have it accessible from within a web server I'v created a symlink from /var/www/cms to /home/vagrant/Projects/joomla-cms. The Joomla 4 installer is now not moving to the next page and I see on the bottom the following warning:

Warning: session_write_close(): Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/home/vagrant/Projects/joomla-cms/installation/sessions) in /home/vagrant/Projects/joomla-cms/libraries/vendor/joomla/session/src/Storage/NativeStorage.php on line 108

When I set the path in the session provider to /tmp then it works.

Steps to reproduce the issue

• Install vagrant
• On your host do vagrant init joomlatools/box
• Then vagrant up
• Log in to the machine like ssh vagrant@33.33.33.58
• Go to the folder /home/vagrant/Projects/
• git clone https://github.com/joomla/joomla-cms.git or use your fork url
• git checkout 4.0-dev
• ln -s /home/vagrant/Projects/joomla-cms /var/www/cms
• Open the browser with the url 33.33.33.58/cms

Expected result

No error message and the installer should jump to the second page when I fill all the data and click next.

Actual result

The installer stays on the first page.
