We have some engines which are installed from separate packages. When it happens, they also install additional configs with plugin-load-add=ha_engine options.

However, upon initial installation apparently these config files are created after the server is started; so, upon first automatic startup after installation the server still does not have them, which seems confusing. I suppose it needs to be fixed somehow.

I've set the affected version to 10.2 because that's where I encountered it, but probably other ones are also affected.

To reproduce:

• enable MariaDB repo, e.g. 10.2
• run apt-get install mariadb-server mariadb-plugin-rocksdb
• check that the server is running, but it doesn't have RocksDB
• restart the server – now RocksDB is there
