This issue tracks documentation improvements for startup_script_behavior (previously, login_before_ready).

The following sections in Templates need improving:

• Coder agent
  • Explain why startup_script_behavior => blocking is a good idea
  • Recommend writing startup scripts that inform the user of what's happening, e.g. echo "Synchronizing /home ..."
  • Mention the importance of & in text (outside of code comments) and mention that >/dev/null 2>&1 may be required to prevent startup script from hanging at the end
• Agent does not become ready
  • Mention all bypass methods (e.g. environment variables) and make the documentation more focused on fixing the issue
