Symptom & Impact

A critical daemon is disabled or exits during boot, causing outages until manual restart.

Environment & Reproduction

Usually appears after configuration edits or package upgrades.

service -e
service myservice onestart
grep myservice /etc/rc.conf

Root Cause Analysis

Incorrect rc.conf knobs, missing runtime directories, or startup ordering dependencies prevent service initialization.

Quick Triage

Capture service logs and rc order quickly.

service myservice status
tail -n 100 /var/log/messages
rcorder /etc/rc.d/* /usr/local/etc/rc.d/* | tail

Step-by-Step Diagnosis

Validate script requirements and runtime prerequisites.

sh -x /usr/local/etc/rc.d/myservice checkconfig
grep -E 'PROVIDE|REQUIRE' /usr/local/etc/rc.d/myservice
ls -la /var/run

Solution – Primary Fix

Fix rc.conf values, create required paths, and restart with proper dependencies.

Solution – Alternative Approaches

Wrap startup in a local rc.d shim for delayed dependency readiness or use daemon supervision.

Verification & Acceptance Criteria

Service starts cleanly across reboots and remains stable.

service myservice status
reboot
service myservice status

Rollback Plan

Restore prior rc.conf and service script if regression appears.

cp -a /etc/rc.conf /etc/rc.conf.rollback
cp -a /usr/local/etc/rc.d/myservice /usr/local/etc/rc.d/myservice.rollback

Prevention & Hardening

Track rc settings in version control and test boot paths after each maintenance window.

Related to port conflicts, permission-denied runtime files, and late-mounted filesystems.
