Both RH and Gentoo have now adopted the upstream systemd units, which don't include "nfs.service". But RH creates an "nfs.service" alias to "nfs-server.service" so as not to upset RHEL sysadmin muscle memory and scripts. > Turns out the foreign RedHat file was starting rpcbind for me all those > months and, when I deleted it last night, rpcbind didn't get started this > morning by nfs-server.service from gentoo (which I think is a bug). Does rpcbind.target exist? Does rpcbind.service have a "Requires" or "Wants" for rpcbind.target? Is rpcbind.service enabled? > #cat nfs-server.service > [Unit] > Description=NFS server and services > Requires= network.target proc-fs-nfsd.mount rpcbind.target > Requires= nfs-mountd.service > Wants=rpc-statd.service nfs-idmapd.service rpc-gssd.service > rpc-svcgssd.service > Wants=rpc-statd-notify.service > > After= network.target proc-fs-nfsd.mount rpcbind.target nfs-mountd.service > After= nfs-idmapd.service rpc-statd.service > After= rpc-gssd.service rpc-svcgssd.service > Before= rpc-statd-notify.service > > [Service] > EnvironmentFile=/etc/conf.d/nfs > > Type=oneshot > RemainAfterExit=yes > ExecStartPre=/usr/sbin/exportfs -r > ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS > ExecStop=/usr/sbin/rpc.nfsd 0 > ExecStopPost=/usr/sbin/exportfs -au > ExecStopPost=/usr/sbin/exportfs -f > > ExecReload=/usr/sbin/exportfs -r > > [Install] > WantedBy=multi-user.target > > I can see that rpcbind.target is Required, but NOT rpcbind.service.
