            I don't think we claim anywhere in documentation that mysql_install_db (or any binaries or scripts other than mysqld and mysqld_safe) use UMASK_DIR variable. However, it does sound like a valid request. The script can very well be made aware of an environment variable, and if we choose on legacy reason to create mysql directory within the script, it should obey the same rules as the rest of the datadir.

            Assigning to serg to decide whether it should be treated as a bug or a feature request, since the procedures are essentially different.
