Ansible blockinline with item list

blockinfile_list_example.yml

# without a marker for each iteration blockinlist will only write the last list entry in the file
# this example shares the directories huhu and haha in the /tmp dir via samba 
- hosts: all
  vars:

Thank you for this! I had to tweak it a bit to keep sections from being repeatedly added.

Instead of

marker: "### config for {{ item.name }}"

I had to add the `{mark}' variable like so:

marker: "### {mark} config for {{ item.name }}"
