People tend to just stuff all file systems into /etc/exports, without
bothering to mark them read-only.  They tend to put '+' in hosts.equiv.
That works fine as long as root owns everything of power, since the
defaults have root not going thru hosts.equiv and being converted to some
notion of 'nobody' over NFS.

There is the new 'read-most' stuff in /etc/exports, but how many will use
it?  How many will use 'nohide' and simply export /?

It may be possible to put together a secure system with bin owning things
(as secure as any UNIX system), but it certainly requires more care than
most users/adminsistrators are willing or able to give.
