WordPress auto update for core but use local package

A list of options, easier ones first.

  1. Run WordPress as a multisite network, you can find instructions here: http://codex.wordpress.org/Create_A_Network

  2. Manually apply changes via .zip file and overwriting.

    • Download latest zip from wordpress.org
    • Make a backup of your file base per install
    • Unpack the zip files then overwrite files in wp-admin and wp-includes.
    • Overwrite root files but make sure you do not change your wp-config.php settings. It’s best to compare the new wp-config for any changes that might have been made so you can apply them.
    • Check wp-content for any new changes and apply them (do not overwrite your
      existing files)
  3. Using Symbolic Links, this isn’t easy will probably break stuff.
