I just install MariaDB on a clean Debian 7 machine. When I want to run mysql_install_db, I get this set of errors:

150329 18:03:07 [ERROR] InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

I looked into error 11, which means "EAGAIN" according to the MySQL 5.6 docs. I'm not sure why this isn't explained about MariaDB, as I have no clue what to do next. Who helps me out?
