The "system user" identifies internal tasks spawned by the server. See here... https://stackoverflow.com/questions/10330159/mysql-system-user Never tried to create a user called this so no idea if it's reserved... but not really a good idea anyway.

What is the meaning of “system user” in the output of this command? Is there a list of these “special” values for the User column? Are these reserved names (i.e., no DB user should be named “system user”)? Thank you! -FG _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : maria-discuss@lists.launchpad.net Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp
