Upgrading to a newer Drupal minor version

Doing some more Drupal recently I needed a way to quickly update my 6.10 Drupal sites to 6.11. The best way that I have found which seems to be safe was found on this Drupal discussion. The steps go like this:

1. Backup your database.
2. Go user ID 1 and Maintenance mode.
3. Switch to Garland.
4. Disable all custom and contributed modules.
5. Use Grsync (or rsync) to synchronize the versions. (I'm using plain old FTP, Filezilla, because I'm crazy like that.)
6. Run update.php.
