Installing system via NFS: permission denied

[Thomas Mueller]

Is it possible to install/update FreeBSD system where the target system is on an NFS share? 

I tried, building 11.0-STABLE from an old 11-current (amd64) and attempting to install over a 10.1-STABLE system over NFS after successfully doing the same update to a 10.1-STABLE system on the same computer, mounted on /media/zip0 and using DESTDIR as needed. 

Would what worked on another partition on the same computer work on a partition on another computer mounted via NFS?

I tried (new system already built), but got messages unlike what I got in the previous log, beginning with "rm:" and ending with "Permission denied".

Failed command was

make installkernel KERNCONF=SANDY11NC DESTDIR=/media/zip1 |& tee installkernel.log

Is the something peculiar about NFS that causes this problem, and is there any safe way around it?

This seems like a problem that would not be peculiar to current or stable branches of FreeBSD.

I looked at the permissions under /boot/kernel/kernel with "ls -l" and didn't find any difference that would explain my failure.

This is what I got
