 When disabling the system FIPS mode the system crypto policy is switched
 to DEFAULT and the kernel command line option 'fips=0' is set.
 
+On transactional systems, enabling the system in FIPS mode with the
+fips-mode-setup tool is not implemented. To enable the FIPS mode in these
+systems requires the following steps:
+
+	1.- Install the FIPS pattern on a running system:
+	    # transactional-update pkg install -t pattern microos-fips
+
+	2.- Reboot your system.
+
+	3.- Add the kernel command line parameter fips=1 to the boot loader
+	    configuration. To do so, edit the file /etc/default/grub and add
+	    fips=1 to the GRUB_CMDLINE_LINUX_DEFAULT variable.
+
+	4.- After logging in to the system, run:
+	    # transactional-update grub.cfg
+
+	5.- Reboot your system.
