Description:
Currently, the SET VARIABLES is used to update in memory only. Permanent changes should be made in the configuration file only.

I suggest you provide an option to update the coniguration file using the SET VARIABLES similar to the SCOPE option in Oracle database so may somethine like this:

SET VARIABLE param_name = param_value PERMANENT

How to repeat:
it's a suggestion

Amongst other issues with this idea,
which file would you write to if the 
!include / !includedir features are
used in my.cnf?

what I meant is avoid to touch the physical files and just do everything using the SQL just like Oracle Database so instead of changing a variable or parameter in my.cnf I should be able to SET it and make the SCOPE=FILE or BOTH or whatever so it will be permanent without having to edit a file.
