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
not helping too?

Well, systemd probably a handy tools to aid. One could check the directory
list of /etc/systemd/system/
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 ^^
