- Swap role includes: sys-systemctl → sys-service in all roles
- Rename variables everywhere: systemctl_* → system_service_* (incl. systemctl_id → system_service_id)
- Templates: ExecStart now uses {{ system_service_script_exec }}; add optional RuntimeMaxSec via SYS_SERVICE_DEFAULT_RUNTIME
- Move SYS_SERVICE defaults into roles/sys-service/defaults (remove SYS_SERVICE_ALL_ENABLED & SYS_SERVICE_DEFAULT_STATE from group_vars/07_services.yml)
- Tidy group_vars/all/08_timer.yml formatting
- Introduce roles/sys-daemon:
- default manager timeouts (timeouts.conf)
- optional purge of /etc/systemd/system.conf.d
- validation via systemd-analyze verify
- handlers for daemon-reload & daemon-reexec
- Refactor sys-timer to system_service_* variables (docs and templates updated)
- Move filter_plugins/filetype.py under sys-service
- Update meta/README to point to official systemd docs
- Touch many roles (backup/cleanup/health/repair/certs/nginx/csp/wireguard/ssd-hdd/keyboard/update-docker/alarm compose/email/telegram/etc.) to new naming
BREAKING CHANGE:
- Role path/name change: use `sys-service` instead of `sys-systemctl`
- All `systemctl_*` vars are now `system_service_*` (e.g., on_calendar, state, timer_enabled, script_exec, id)
- If you have custom templates, adopt RuntimeMaxSec and new variable names
