No. The correct way to do this is to replace the current code
fs_locations handler so that we do the mount from userspace. In addition
to voiding the whole issue of in-kernel DNS resolution, that also has
the benefit that it allows us to put policy decisions like which server
to mount from under administrator control in userspace.

I've already started coding up a solution.
