Debian is a free operating system (OS) that comes with over 29000 packages, precompiled software bundled up in a nice format for easy installation on your DiskStation. Debian Chroot allows you to benefit from the Debian OS inside your DiskStation, alongside DSM. This package is intended for advanced users only.
Once the installation finished in the Package Center, it continues in the background and you can see its status to Installing under Overview in the left pane. The installation finished, the status will automatically change to Installed.
In the same pane, you can monitor how many services are running and perform update operations.
As soon as the status is Installed, you can start using the chroot. To do so, connect to the DiskStation through SSH (root user) and use the following command: /var/packages/debian-chroot/scripts/start-stop-status chroot.
On the first use, it is recommended to perform some configuration operations:
Debian Chroot allows you to manage the packages you installed in the chroot directly from DSM.
Under Services in the left pane, you can manage services that you manually installed previously in the chroot: start and stop them easily.
