Disable Mounting of hfs

An XCCDF Rule

Description

To configure the system to prevent the hfs kernel module from being loaded, add the following line to the file /etc/modprobe.d/hfs.conf:

install hfs /bin/true

This effectively prevents usage of this uncommon filesystem.

Rationale

Linux kernel modules which implement filesystems that are not needed by the local system should be disabled.
