Systemd to Remove Unwanted Service or Daemon During Startup

Have you ever experiencing sticky or annoying service or daemon that runs during startup? Removing with update-rc.d -f <service_name> remove does not work and maybe by changing the file name in rc-X.d/ not helping too? Well, systemd probably a handy tools to aid. One could check the directory list of /etc/systemd/system/multi-user.target.wants/ If one could see list of files there, then could remove the file by e.g # systemctl disable rpcbind And so on. Hope it helps ^^
