Both of those PRs should be closed as not-a-bug, I think.  nfsiod
threads simply allow multiple concurrent NFS requests.  In 4.*, with
no
nfiod processes running, you can still use NFS (just more slowly
than
with them).  In 5.*, they are auto-created as kernel threads during
bootup.

They aren't tasks, but kernel threads.  Just like pagedaemon,
swapper,
g_event, irq*, swi*, and a couple dozen other threads created by the
kernel.

Why not?  If you want to disable NFS, that's the only way.

You did not answer my question.
how can I kill these bogus nfs tasks as part of the boot up or what
to change in the boot up process so these tasks don't get started in
the first place?  What is a work around with out compiling the
kernel?
