WalkthroughThis PR migrates infrastructure provisioning from an external Linuxbrew role to a custom Debian-native Homebrew implementation. It modernizes APT repository management across CrowdSec and Docker tasks, enables local playbook execution for dev hosts, adds safety checks to role execution, and updates documentation and tooling.

Inline comments:
In `@ansible/apply-localhost.sh`:
- Around line 4-7: The script ansible/apply-localhost.sh currently hardcodes
--limit "$(hostname)" which fails when inventory uses an alias; change the
wrapper to allow an override (e.g. read a LOCAL_HOST or LIMIT env var or accept
a first positional parameter) and fall back to $(hostname) only if no override
is provided, then pass that value into the ansible-playbook --limit flag; also
add a simple validation to error out if the resolved limit is empty to avoid
silently skipping the run (update the ansible-playbook invocation that currently
contains --limit "$(hostname)" and maintain support for passing through "$@" as
before).
In `@ansible/README.md`:
- Line 25: Update the README instruction to use the same bootstrap path as
docs/setup.md by referencing the script with its relative path from the
repository root (ansible/bootstrap-ansible.sh) instead of just
bootstrap-ansible.sh; modify the line that currently shows "sudo
bootstrap-ansible.sh" to "sudo ansible/bootstrap-ansible.sh" so the command
works without requiring users to cd into the ansible/ directory.
In `@ansible/roles/debian_base/tasks/70-user.yaml`:
- Around line 27-38: Replace the current non-fatal "Warn if SSH key file is
missing" behavior with a hard failure when both the SSH key and admin password
are absent: after the ansible.builtin.stat that registers
debian_base_ssh_key_stat, add an ansible.builtin.fail task (or change the debug
task) that triggers when not debian_base_ssh_key_stat.stat.exists and
(admin_password|default('') == '') and include a clear message referencing
admin_user and debian_base_ssh_key_file; keep the existing conditional that
skips the authorized_key task (when: debian_base_ssh_key_stat.stat.exists)
intact so key setup still proceeds only when the file exists.

- Line 38: Update the stale inline comment that currently reads "Linuxbrew" to
"Homebrew" so it matches the role name debian_homebrew and clarifies that the
Homebrew installation is per-user; locate the comment line "### Setup additional
roles (Linuxbrew installation is per-user)" in the .devcontainer/Dockerfile and
replace "Linuxbrew" with "Homebrew".
In `@ansible/roles/debian_base/tasks/50-crowdsec.yaml`:
- Around line 9-23: The apt repo added by the "Add crowdsec apt repository"
deb822_repository task isn't available to the immediately following "Install
crowdsec iptables bouncer" apt task because handlers (the "Update apt cache"
handler) run later; fix this by forcing the handler to run before the
install—insert a meta: flush_handlers task immediately after the "Add crowdsec
apt repository" task (or alternatively set update_cache: yes on the "Install
crowdsec iptables bouncer" ansible.builtin.apt task) so the APT cache is
refreshed from the new repo before attempting to install
crowdsec-firewall-bouncer-iptables.
In `@ansible/roles/debian_docker_host/tasks/10-docker-Ubuntu.yaml`:
- Around line 4-14: The Ubuntu apt task "Install required system packages" using
ansible.builtin.apt is missing the python3-debian package required by the
deb822_repository module; update the pkg list in that task (the one named
"Install required system packages") to include python3-debian so the later
repository tasks can import deb822 successfully.
In `@ansible/roles/debian_samba_client/tasks/10-samba.yaml`:
- Around line 9-23: The tasks "Warn if admin_password is not set" and "Create
credentials file" currently only check admin_password is defined; change both
conditions to treat an empty string as missing by using the same check as
elsewhere (e.g., admin_password|default('') != '' or admin_password|default('')
| length > 0). Ensure the warning task triggers when admin_password is undefined
or empty, and ensure the credentials file task only runs when admin_password is
non-empty; keep references to debian_samba_client_credentials_file, admin_user
and admin_password when updating the when clauses.
