Mariadb service not starting on macOS

[JoyceBabu]

What happened?

mariadb service fails to start on macOS. The following command is not working

mysqld --log-error=$MYSQL_HOME/mysql.log & MYSQL_PID=$! && echo 'Starting mysqld... check mariadb_logs for details'

It works if I remove the & MYSQL_PID=$! assignment

Interestingly, the command works when directly executed in terminal.

Usually MYSQL_PID is immediately defined, when you need to wait on the process, or to call killall $MYSQL_PID after calling mysqlshutdown. Since devbox is using neither of them, is it required?
