An
administrator can explicitly enable a daemon, set its arguments, user,
login class, routing table, working directory, logging, or timeout,
test its configuration, and list enabled-but-failed or
disabled-but-running services. Daemon enablement is represented explicitly in configuration, site
overrides remain in one upgrade-safe text file, and a daemon's
configured identity and resource class are easy to inspect.
