This option allows administrators to restrict a specific domain's user environment using Jailkit, thereby potentially enhancing security by isolating it from the complete system.

When enabled, the domain's associated Unix user will be placed in a chrooted environment using Jailkit. This means the user will only have access to a limited set of resources, defined by the Jailkit configuration.

Jailkit configuration utilizes the settings from the `jk_init.ini` configuration file to determine which files, binaries, and libraries are accessible within the chrooted environment. Additional configurations, such as extra sections or commands, can also be defined as needed.

Before enabling Jailkit for a domain, ensure you understand the implications. Users might experience limitations in accessing certain system resources or executing specific commands.
