On the dependency side, you should drop the "Wants" (it is not needed)
and replace After with:
After=network.target 

(this will ensure network is up before starting kinit).

You also should ensure kinit.service is enabled (running systemctl
enable kinit.service one time). This should be enough to have this unit
started each time 3min after booting is complete (please note systemd
doesn't make any difference between initial boot and reboot in the
startup sequence).
