It's all default both in fstab and as reported by mount(8). This is a diskless PXE boot but the mount affected (usr) is not the root filesystem, so this should come in via fstab. BTW, my /usr/ports is another mount so the corruption is cross-mount (garbage from /usr/ports entering /usr). Appending nfsstat output. I am re-running things contiguously to see how reproducible this is. This machine was recently updated from a -current almost a year old, so it's its first time with the new NFS client code.
