The system image contains read-only files and directories such as `/bin`. A new one is released with each new Python version. To upgrade it, you have to contact the staff in the forums or by using the "Send Feedback" link on the website. All system images have Python 2.6, 2.7, and at least 3.3. These are the system images:

  * classic: 3.5
  * dangermouse: 3.6
  * earlgrey: 3.7
  * fishnchips: 3.8 (not released yet)

The naming scheme follows an alphabetical pattern just like stupid Android, and the theme is British stuff.

## Benefits

System images provide the following benefits:

  * The files in the system image do not count against the disk quota.
  * You do not have to install things yourself if they are part of the system image.


## What is installed

System images have lots of things pre-installed.
