005 Remove old journal files
Use the following command in a terminal window to clear out all journal files older than 1 day, this recovers quite a bit of HDD space:

Scripts can be placed in the following directory so you don't have to include the full path:
  • /usr/local/bin

Find "load-module" and comment it out by adding a # to the front of the line
