You can 'piggy back' it on the next real bump. There will be a small period of time where the feature is, in fact, on the system, but this will likely give you sufficient fidelity to know for sure.

Among other things, it's now possible to use unmodified userspace binaries (rpcbind, mountd, nfsd) to start a rump nfs service and mount file systems from it. pain-rustique:42:~> mount rumpfs on / type rumpfs (local) 10.1.1.1:/export on /mnt type nfs Cool. Is it possible to have anita booting NetBSD in qemu with root on nfs? Christoph
