This is best used on systems without an initrd that 10 have a root filesystem backed by a read-only device such as 11 dm-verity or a CDROM. 12 13config SECURITY_LOADPIN_ENFORCE 14 bool "Enforce LoadPin at boot" 15 depends on SECURITY_LOADPIN 16 help 17 If selected, LoadPin will enforce pinning at boot.
