Have you seen the opscode database recipe that does most of this across three or four platforms? https://github.com/opscode-cookbooks/database

@DenisBY

OpsCode's cookbook requires to install ruby and mysql gem. Why I need them on my DB server?

@frankflynn

This seems to only offer granularity at the database level, nothing at the table level. So I could not have a users with SELECT on db1.table1 and SELECT, UPDATE on db1.table2.

I do like the way you run DROP USER before (if you did not do that old users would stay around forever).
