What runlevel is typically used for normal multi-user operations in Debian-based systems?

In Debian-based systems, runlevel 2 is typically used for normal multi-user operations. This runlevel allows multiple users to log in, while the system provides essential services like networking, which facilitates interactions over the network. Unlike some other distributions that may commonly use runlevel 3 or 5 for multi-user operations, Debian's design defaults to runlevel 2, which is a multi-user mode without a graphical interface.

Runlevel 2 enables a wide range of features to support user operations, such as various services and daemons that are important for system tasks. It is important to note that this setup does not include a graphical user interface (GUI), making it suitable for server environments or situations where resources are better allocated without a GUI overhead.

This understanding of runlevels is valuable for system administrators to manage the operational state of their Linux systems effectively, taking into account specific needs for services and user access.
