A machine mounts what its assignment names: a node's share from the provision nfs-share, whose path it reads from nfs-server's state on the bus, and occasional sources (an SMB device, a disk) whose absence is a state, not a fault. apply writes and arms the unit pairs as root; watch tries each source and judges the health; the operator's fstab lines are taken over only through adopt, on their word, once the replacement is armed. SMB logins are an outside party's secret, given with secret accept.
