Editing hosts & hosts.editable has no effect

I am sorry to bring this thread up but the solution in this thread was not satisfying me. As @Seven.of.nine I did not get it what the solution is. So I looked up in the forum for a thread and found that discussion

Problem: [release notes] Koli 4.0.1 - #75 by martijntje
Explanation/Solution:
-Part 1 [release notes] Koli 4.0.1 - #119 by martinh
-Part 2 [release notes] Koli 4.0.1 - #125 by martinh

My /etc/nsswitch.conf and /etc/resolv.conf does exist, so as I understand @martinh my /etc/hosts file should be considered.

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
#

passwd:         db files
group:          db files
initgroups:     db [SUCCESS=continue] files
shadow:         db files
gshadow:        files

hosts:          files dns
networks:       files dns

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       db files
# Generated by Connection Manager
nameserver ::1
nameserver 127.0.0.1

I am not sure how to move one. Does anyone has an idea? I tested this even with a small /etc/hosts file, which just has an extra entry like this:
0.0.0.0 jolla.com
Still no success.
