That's what I thought at one point, but it's set on almost everything,
including mount, open with or without O_CREAT, mknod, mkfifo, link,
symlink, mkdir, and rename, and also unlink and rmdir.

If that's not how it should be, things should be tidied up. (And, if
neither mkdir-type nor rmdir-type operations should have TRYEMULROOT,
my original question becomes largely or entirely moot.)
