The command systemctl enable rpcbind.service seems not work. The rpcbind.service does not start after rebooting.
systemctl enable rpcbind.service
How to make/force the rpcbind.service auto start in systemd on Linux?
You an force the rpcbind.service to start by making it be "wanted" by the target such as multi-user:
# systemctl add-wants multi-user rpcbind.service
This will force rpcbind.service to start.
