Preseed Action

The preseed action defines the contents of the <profile>.preseed file. This file will contain the preconfiguration for the Debian installer. The preseed action takes in a jinja template of the preseed file, in which chosen configuration parameters are replaced with jinja variables. Finally, it replaces the parameters with the provided substition variables.

Tip

Check out the Debian documentation on the contents of the preconfiguration file to learn more about the preseed file.
