See summary. That's wrong and it will break thinks if you are currently 
exporting directories because current state is lost. Since we can't upgrade 
nfs-utils only after stopping the service I suggest to protect all files in 
/var/lib/nfs.

could easy be done with config_protect

I've now fixed this in nfs-utils-1.0.6.ebuild (without bumping the rev).  The fix is simply to install the original versions of the files in /usr/lib/nfs for safekeeping.  pkg_postinst will install them in /var/lib/nfs if there are no existing files.  I think this is better than CONFIG_PROTECT since it's rare that you'd want to "merge" the distributed xtab and friends with your existing version.

Thanks for the bug report!
