Ang solusyon ay ang pag-edit/lib/systemd/system/monit.service:

[Unit]
Description=Pro-active monitoring utility for unix systems
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/monit -I
ExecStop=/usr/bin/monit quit
ExecReload=/usr/bin/monit reload

[Install]
WantedBy=multi-user.target

at idagdagnfs.servicesaAfterSa likod.Ang huling resulta ay ganito ang hitsura:

[Unit]
Description=Pro-active monitoring utility for unix systems
After=network.target nfs.service

[Service]
Type=simple
ExecStart=/usr/bin/monit -I
ExecStop=/usr/bin/monit quit
ExecReload=/usr/bin/monit reload

[Install]
WantedBy=multi-user.target

Ang Monit monitor ay maaari nang magsimula nang matagumpay sa oras ng boot.
