title: 'Disable Mounting of cramfs'

description: |-
    {{{ describe_module_disable(module="cramfs") }}}
    This effectively prevents usage of this uncommon filesystem.

    The <tt>cramfs</tt> filesystem type is a compressed read-only
    Linux filesystem embedded in small footprint systems. A
    <tt>cramfs</tt> image can be used without having to first
    decompress the image.

rationale: |-
    Removing support for unneeded filesystem types reduces the local attack surface
    of the server.
