service_state
Maintains the ansible/roles/service_state Ansible role that masks/unmasks, enables/disables, and restarts/reloads systemd units by declarative lists, as part of the Linux SOE. Use when checking or fix
SKILL.md.claude/skills/service_state/SKILL.md
GitHubservice_state
Maintains ansible/roles/service_state/. See docs/ARCHITECTURE.md for the shared
conventions (role layout, audit vs. remediate via --check --diff, safety
rules, branch + PR contribution workflow).
ansible/roles/service_state/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/service_state/
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/service_state/policy-<short-desc>orsoe/service_state/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/service_state/defaults/main.yml:
- Four independent lists, all defaulting empty:
service_state_mask/_unmask/_disable/_enable, plusservice_state_restart(restart by default per entry, orstate: reloadedwith an optionalrequire:precondition on current state). sshd/sshd.serviceare hard-excluded from mask and disable/stop regardless of what's listed — the role won't let you lock out SSH access to itself.- An item in both
service_state_maskandservice_state_unmask, or bothservice_state_disableandservice_state_enable, resolves to "unmask"/"enable" winning. service_state_skip_missing(defaultfalse) — an enable/start entry for a unit that doesn't exist fails the role by default; settrueto skip it instead.
This role is sourced from the myllynen/rhel-ansible-roles import
(see git log -- ansible/roles/service_state) 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 service_state --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 service_state
Propose a change to the role itself: never edit and commit directly. On a
branch named soe/service_state/<short-desc>, edit ansible/roles/service_state/, validate
locally (--syntax-check, ansible-lint roles/service_state/, and
--check --diff against a real/test host if available), then push and open a
PR titled [service_state] <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
- Masking a unit prevents even manual
systemctl startuntil unmasked — confirm the mask list doesn't include anything another role in this repo (e.g.usbguard_setup,audit_setup) depends on being startable.
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)
for the general host baseline, and has a row in
.claude/skills/soe/SKILL.md's domain table, so it runs as part of both
ansible-playbook ansible/configure_rhel.yml --tags service_state ... and a full,
untagged ansible-playbook ansible/configure_rhel.yml run. This repo no longer
uses ansible/site.yml as the baseline entrypoint — see docs/ARCHITECTURE.md.
The same role is also invoked by ansible/load_balancer_setup.yml and ansible/nfs_client_setup.yml and ansible/nfs_server_setup.yml, each with its own
purpose-specific variables set directly in that playbook (not this role's
defaults/main.yml) — e.g. a different package list or file/service set for a
load balancer or NFS host than the general baseline uses. When asked to
audit/remediate service_state on a host, check which of these playbooks actually
applies to that host's role before picking one; running the wrong playbook's
vars against it reports drift against the wrong intent.
