Gah! Of course. known.stdout_lines is a list, so
loop:
- '{{ known.stdout_lines }}'
passes the whole list as a single item. So you need to not put the list
in a list:
loop: '{{ known.stdout_lines }}'
should do the trick.

I wonder if *[ *in *[/root/.ssh/known_hosts* is getting in the way,
since */root/.ssh/known_host* does exist.

You want stdout_lines rather than stdout. The former is a list
with new-lines removed. The latter is a possibly very long string
with the complete output stream intact.

Good day, all. I hope I'm not wearing out my welcome with too
many questions.
In the following playbook, I first find any know_host file for
any user on a particular system. I then copy a file with the list
of additions to add to the known_hosts files. What I want to do
is use the output of my register values to make changes to those
know_host files, which my last play does. My iteration is wrong,
though.
The playbook:
*---
- hosts: all
gather_facts: false
become: yes
vars:
script_path: <script>
tasks:
- name: Find known hosts
shell: find /root /home -type f -name known_hosts
register: known
- name: Debug known_hosts paths
debug:
msg: "{{ known.stdout }}"
- name: Set fact with known_hosts paths
set_fact:
known_hosts_paths: "{{ known.stdout_lines }}"
- name: Upload entries for new known_hosts svn
copy:
src: append
dest: /tmp/append
owner: root
group: root
mode: u=rwx,g=rw,o=rw
- name: Append to all known_host files
shell: cat /tmp/append >> {{ item }}
loop:
- '{{ known.stdout }}'*
The output of the first play:
*ok: [myhost] =>
msg: |-
/root/.ssh/known_hosts
/home/user1/.ssh/known_hosts
/home/ user2/.ssh/known_hosts
/home/ user3/.ssh/known_hosts
/home/ user4/.ssh/known_hosts*
How do I make that last play work? --
