Any files read through the kernel file reading interface
|
|
(kernel modules, firmware, kexec images, security policy)
|
|
can be pinned to the first filesystem used for loading. When
|
|
enabled, any files that come from other filesystems will be
|
|
rejected. This is best used on systems without an initrd that
|
|
have a root filesystem backed by a read-only device such as
|
|
dm-verity or a CDROM.

If selected, LoadPin will enforce pinning at boot. If not
|
|
selected, it can be enabled at boot with the kernel parameter
|

"loadpin.enforce=1".
