Description:
If you try to initialize a datadir when MySQL is configured with the keyring_file_data option, the initialization fails with

   [ERROR] unknown variable 'keyring_file_data=/mysql/spool/keyring'

How to repeat:
1. Setup my.cnf

[mysqld]
# Paths
basedir           = /usr/local/mysql
datadir           = /mysql/data
socket            = /mysql/spool/mysql.sock
pid_file          = /mysql/spool/mysql.pid
keyring_file_data = /mysql/spool/keyring

2. Initialise MySQL:

   shell$ /mysqld --defaults-file=my.cnf --initialize --log_error=install.log

3. Initialisation failed:

   shell$ cat install.log

Suggested fix:
Support the keyring_file_data option so the configuration of MySQL can be completed before initialisation.

The workaround is to initialise MySQL without the keyring_file_data option, then add it before starting MySQL (or restart MySQL is it's already started).

Noted in 5.7.13 changelog.

Starting the server with --initialize failed if the keyring_file_data
system variable was also set at startup. To handle this, with
--initialize the server no longer skips registration of plugins
loaded with the --early-plugin-load option.
