Creating archive disabled by the php.ini setting phar.readonly

[jmolivas]

I am currently testing JoliCI for Drupal Console project and the default container php.ini setting for creating archive .phar files is disabled and I am getting the following error message:

[UnexpectedValueException]
creating archive "/home/project/console.phar" disabled by the php.ini setting
phar.readonly

This is the Drupal Console project travis file
https://github.com/hechoendrupal/DrupalAppConsole/blob/master/.travis.yml#L22

There is any plan to change the container php.ini configuration to

phar.readonly = false
