Description

SASL is now disabled correctly. The Dockerfile has been adjusted to not show the delaying debconf because apt-utils is not installed error anymore. function _misc_save_states was refactored too as it was in an unacceptable state. Especially proud of the inline variable substitutions that got rid of echo ... | sed ....
