GitHubsystem_init
Maintains ansible/roles/system_init/. See docs/ARCHITECTURE.md for the shared
conventions (role layout, audit vs. remediate via --check --diff, safety
rules, branch + PR contribution workflow).
ansible/roles/system_init/README.md documents this role's full
configuration surface (every defaults/main.yml variable, with its
original inline comments, rendered as a single reference). Read it
before proposing or explaining how to configure this role — it
reflects the role's actual current defaults even if a variable summary
elsewhere in this file has drifted out of sync with the role.
Policy & workload awareness
docs/VERTICAL_POLICY.md, docs/HORIZONTAL_POLICY and docs/WORKLOAD.md capture org-wide policy items and
the workloads this SOE actually hosts — either can gain a new or changed
item that this role should reflect. Before auditing, remediating, or
proposing a change, check whether either doc has changed more recently
than this role's own code:
git log -1 --format='%cI %h %s' -- docs/VERTICAL_POLICY.md docs/HORIZONTAL_POLICY.md docs/WORKLOAD.md
git log -1 --format='%cI %h %s' -- ansible/roles/system_init/
If the docs' latest commit is newer than the role's, this role hasn't been re-assessed against current policy/workload — read both files and judge whether anything added or changed since is relevant to this domain:
- Relevant — propose a concrete change on a branch
(
soe/system_init/policy-<short-desc>orsoe/system_init/workload-<short-desc>), same branch + PR workflow as any other role change (see "What to do" above anddocs/ARCHITECTURE.md's "Contribution workflow"). Don't wait to be asked. - Not relevant — say so explicitly (e.g. "checked against
docs/VERTICAL_POLICY.md,docs/HORIZONTAL_POLICYanddocs/WORKLOAD.mdas of<date>, nothing affecting this domain") rather than silently skipping the check.
This check is informational, not a gate — it runs alongside a normal audit/remediate, never blocks one; surface the staleness note alongside the normal output.
What the role actually does
Encoded in ansible/roles/system_init/defaults/main.yml:
system_init_final_actions(default:[reboot, syslog]) —localhostis excluded from the reboot action regardless of this list (per the role's own default comment).
This role is sourced from the myllynen/rhel-ansible-roles import
(see git log -- ansible/roles/system_init) rather than hand-authored for this
repo. Unlike the original reference domains (e.g. timesync, usbguard_setup),
it applies state declaratively via standard Ansible modules and does not
add its own assert-based drift checks on top — an audit here is exactly
what --check --diff reports from the underlying modules, nothing more.
What to do
Audit (read-only, safe to run any time):
ansible-playbook ansible/configure_rhel.yml --tags system_init --check --diff
Summarize the diff output and any failed tasks in plain language.
Remediate (modifies the system — only after the user explicitly asks):
first summarize what will change from the --check --diff output, then run
the same command without --check:
ansible-playbook ansible/configure_rhel.yml --tags system_init
Behavior change from the old
ansible/site.yml: this role is now active by default inansible/configure_rhel.yml'sroles:list — unlike the old baseline playbook, which deliberately excluded it (see "Wiring into the SOE" below). A full, untaggedansible-playbook ansible/configure_rhel.ymlrun now reboots the host as a side effect, becauserebootis insystem_init_final_actions' default list. Flag this loudly before anyone runs the full baseline playbook without--tagsagainst a host they don't expect to reboot.
Propose a change to the role itself: never edit and commit directly. On a
branch named soe/system_init/<short-desc>, edit ansible/roles/system_init/, validate
locally (--syntax-check, ansible-lint roles/system_init/, and
--check --diff against a real/test host if available), then push and open a
PR titled [system_init] <what changed> with the --check --diff output in the
body. Then stop — a human reviews and merges; see docs/ARCHITECTURE.md's
"Contribution workflow".
Notes
- Because
rebootis in the default action list, running this role for the first time on a host reboots it — confirm before including it in a remediate run, same as any other reboot-by-default role in this repo (boot_parameters... no,boot_parametersis audit-only; thinksystem_locale,ipv6_setup,multipath_setup).
Wiring into the SOE
This role is in configure_rhel_domains's default value in
ansible/configure_rhel.yml (see .claude/skills/configure_rhel/SKILL.md)
— this is the opposite of its old status under ansible/site.yml, where
it was deliberately excluded from the default roles: list (see the
"excluded from the default run" table this repo used to keep in
.claude/skills/soe/SKILL.md) because it acts unconditionally with no
guard variable and reboots the host. That exclusion doesn't apply to
configure_rhel.yml: a plain, untagged
ansible-playbook ansible/configure_rhel.yml run now does reboot the
host via this role. If a host needs configure_rhel.yml's baseline
without the reboot, either run with --tags excluding system_init
(--skip-tags system_init), pass a configure_rhel_domains list that
leaves system_init out, or override system_init_final_actions to
drop reboot for that host/group. Don't assume this role is a safe no-op
the way it was when site.yml was the entrypoint. This repo no longer
uses ansible/site.yml; see docs/ARCHITECTURE.md.
