 (unless the policy has already been set to FIPS plus subpolicies on top,
 in which case the currently active subpolicies is retained).
 
+Some required FIPS modules (grubby, fips pattern) might not be
+installed by default. These can be installed in SUSE/openSUSE with
+the following command:
+
+    zypper in -y grubby && zypper in -y -t pattern fips
+
 Then the command modifies the boot loader configuration to add
 'fips=1' and 'boot=<boot-device>' options to the kernel command line.
+Note that, grubby could show a harmless warning about leaked file descriptors.
 
 When disabling the system FIPS mode the system crypto policy is switched
 to DEFAULT and the kernel command line option 'fips=0' is set.
