• password_file - [ Stdlib::UnixPath ] - Default: /etc/grub.d/50_password - The path to the file containing the bootloader password(s). This is only used if password_protect is true.
• replace_password_file - [ Boolean ] - If true, replaces the password file if it exists with a NEW hash of the password. Also, when set to true, this resource is NOT idempotent. When set to false, this prevent accidental overwriting of the password file with a new hash of the same password.
• hash_superuser_password - [ Boolean ] - Default: true - If true, the superuser password will be hashed using PBKDF2-HMAC-SHA512. If false, the superuser password will be stored in the password file as-is. This is only used if password_protect is true.

• superuser_password_buffer_length - [ Optional[Integer] ] - Default: undef - The length of the resulting hash. Default is 128. This is optional and only used if password_protect and hash_superuser_password are true.
• superuser_password_iterations - [ Optional[Integer] ] - Default: undef - The number of times the password is passed through the hash function. Default is 120000. This is optional and only used if password_protect and hash_superuser_password are true.
• other_users - [ Optional[Array[Struct[{username=>String[1], password=>Sensitive[String], salt_length=>Optional[String], buffer_length=>Optional[Integer], iterations=>Optional[Integer]}]]] ] - Default: undef - An array of structured hashes to add other users besides the superuser to the password file. This is optional only used if password_protect is true. The users specified here will be added to the password file as regular users, not superusers. Other user passwords will be hashed using PBKDF2-HMAC-SHA512, just like the superuser password, if hash_other_user_passwords is true.
