Why each option
On F5 BIG-IP, the zrd and gtmd daemons are license-dependent and will not start until the system has completed the full licensing process.
The zrd (Zone Runner Daemon) is responsible for DNS zone management within BIG-IP DNS and requires a valid license to operate, so it only starts after licensing is complete.
tmm (Traffic Management Microkernel) starts during system boot as part of core packet processing infrastructure and is not gated behind the full license completion process.
ntpd is a standard Linux time-synchronization daemon that starts early in the boot process independently of the F5 license state.
The gtmd (Global Traffic Manager Daemon) is the core GTM process and is gated behind license validation - it will not initialize until the system confirms a valid GTM or DNS license has been successfully applied.
