SELinux has just been installed on a Linux system and the administrator wants to use SELinux in permissive mode in order to audit the various services on the system. What command will switch SELinux i

The `setenforce` command is used to dynamically change the enforcing status of SELinux. Specifically, `setenforce 0` puts SELinux into permissive mode, where it logs policy violations but does not block any actions, making it ideal for auditing.

`/etc/init.d/selinux stop` would completely disable SELinux, which is different from permissive mode and would prevent the auditing of policy violations.

`selinux passive` is not a valid or recognized command for changing SELinux mode on a Linux system; the correct utility is `setenforce`.

`/etc/init.d/selinux startpassive` is not a standard or recognized command to manage SELinux modes, as SELinux modes are controlled via `setenforce` or kernel boot parameters.
