Debian 9 Stretch Chips

There are several chips that we will focus on.

User identification system

Debian 9 can use multiple user identification systems at the same time, such as LDAP, NIS and Hesiod. This makes it easier to configure the system for large corporate networks with a large number of users.

Package Manager support

Debian's package manager, dpkg, supports many additional tools, such as apt, aptitude, apt-rdepends, apt-listchanges, etc. This makes it easier to manage packages on Debian and makes it easier to install and update software.

Automatic parsing of configuration files

Debian 9 automatically parses configuration files during package installation. This makes the process of installing software on Debian less time-consuming and less error-prone.

Open source code

Like most Linux distributions, Debian 9 is open source. This allows users to customize it to perfection and on their own machine.
A large community of users and developers

Debian 9 is one of the largest and most active user and developer communities in the Linux world. This means that you can always find help and advice from other Debian 9 users on the internet.
