True. But let's assume that we're not upgrading from major releases
(4.X to 5.X), as it's even discouraged to do so, but only from the
same minor release/branch (e.g. 5.2.1 to 5.4, or 4.4 to 4.10), I don't
think that NFS-mounting the built sources would not work, as the
build{kernel|world} stage only builds the kernel and world at
/usr/obj. In my own experience, it generally works, in fact, this
doesn't only work for NFS but for remote upgrades as well, I've done
something like building the kernel/world in a ultrafast box, tar
bzip'ing /usr/src and /usr/obj, uploading them unto a remote server
that desperately need to be upgraded and doing the install
kernel/world on that remote server.
