Since Android 14, Android does not use fsverity builtin signatures.
(fsverity remains supported, but signatures are verified in userspace,
or fsverity is used for integrity-only use cases.) Therefore, the only
reason to still run 'fsverity_init --load-verified-keys' at boot time is
to ensure that old files can still be opened, if:
- They were created by Android 13 or earlier, with an fsverity builtin
signature by a key in /{system,product}/etc/security/fsverity/.
- *And*, the kernel still has CONFIG_FS_VERITY_BUILTIN_SIGNATURES=y.
However, it appears that this isn't actually needed anymore. Only two
features could potentially be affected: APK verity and updatable fonts.
APK verity wasn't widely rolled out before being disabled, and updatable
fonts have recovery logic in place for when the files cannot be opened.
And in any case, disabling CONFIG_FS_VERITY_BUILTIN_SIGNATURES in the
kernel is recommended and would avoid any problem.
