On my machine I discovered this in the logs: Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found ordering cycle on nfs-common.service/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found dependency on rpcbind.target/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found dependency on rpcbind.service/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found dependency on rpcbind.socket/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found dependency on sysinit.target/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Found dependency on nfs-common.service/start Jan 26 14:40:14 xxxxxx systemd[1]: nfs-common.service: Breaking ordering cycle by deleting job rpcbind.target/start Jan 26 14:40:14 xxxxxx systemd[1]: rpcbind.target: Job rpcbind.target/start deleted to break ordering cycle starting with nfs-comm Since DefaultDependencies is not disabled, rpcbind.socket ends up depending on sysinit.target. From the above one can see a cycle forming, which is (correctly) solved by throwing out one of the offending units. DefaultDependencies should be set to 'no' for early boot, as is the case for the provided rpcbind.service file. Also rpcbind.socket needs to be updated with these, i.e. by modifying the following lines in its unit section: [Unit] DefaultDependencies=no Conflicts=shutdown.target Before=shutdown.target After=systemd-tmpfiles-setup.service The easiest way of applying the modification is to add the above lines to a .conf file in the /etc/systemd/system/rpcbind.socket.d/ directory. This solved my problem of unmounted krb5p secured NFS /home and other directories on bootup. HTH.
