The freevxfs filesystem type is a free version of the Veritas type filesystem. This is the primary filesystem type for HP-UX operating systems.


Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.


Edit or create a file in the /etc/modprobe.d/ directory ending in .conf
Example: vi /etc/modprobe.d/freevxfs.conf
and add the following line:

install freevxfs /bin/true

Run the following command to unload the freevxfs module:

rmmod freevxfs
