As we move stuff around, some doc references are broken. Fix some of them via this script: ./scripts/documentation-file-ref-check --fix Manually checked if the produced result is valid, removing a few false-positives.

Provide the file name of a private key/certificate in PEM format,

the URI should identify, both the certificate and its corresponding

private key.

Provide a system keyring to which trusted keys can be added. Keys in
|
|
the keyring are considered to be trusted. Keys may be added at will
|
|
by the kernel from compiled-in data and from hardware key stores, but
|
|
userspace may only add extra keys if those keys can be verified by
|
|
keys already in the keyring.

Keys in this keyring are used by module signature checking.

If set, this option should be the filename of a PEM-formatted file

containing trusted X.509 certificates to be included in the default

system keyring. Any certificate used for module signing is implicitly
|
|
also trusted.

NOTE: If you previously provided keys for the system keyring in the

those are no longer used. You will need to set this option instead.
