To allow a specific Boolean for SELinux, what must be set?

To allow a specific Boolean for SELinux, the correct requirement is to set it to an integer value, specifically '1'. In SELinux, Booleans are used to enable or disable various security policies dynamically without having to restart or reload SELinux policies. When a Boolean is set to '1', it indicates that the Boolean is enabled, allowing the associated policy settings to take effect.

Using '0' would disable the Boolean, thus reverting to the previous security restrictions. Therefore, setting a Boolean to '1' is essential when you want to allow a certain permission or feature provided by the SELinux policy. This approach ensures that security configurations can be changed effectively in response to specific requirements or changes in the system environment.

The other options do not accurately represent how Booleans are enabled in SELinux; they might convey a similar idea but lack the precise technical accuracy needed for properly configuring SELinux.
