This discussion belongs in "Support" not Development. Frankly, I won't auto-update anything; I test it first.

If you have drush, you can run `drush pm-update` to automatically update core and contrib.

I'm not sure if I'd build in automatic updating of core in Drupal, though, since it's a bit more complex than updating a module and many more things can go wrong.
