This horrible hack is necessary because Someone(tm) started converting
our NFS client to the new nmount(2) semantics a year ago but he has
never finished the job.  Now the NFS client just uses old mount(2)
semantics over nmount(2) by stuffing all NFS-related options in
"nfs_args" and passing the standard options as bit flags.  At the
same time, the kernel part of the NFS client already relies on
string options instead of bit flags -- ever tried to remount a r/w
NFS mount to read-only since nfs_vfsops.c #1.176?  Hence the hack.

Which else _hacks_ did I commit?
