Subject: Re: kern/147881: [zfs] [patch] ZFS "sharenfs" doesn't allow different \
                "exports" options for different hosts
Date: Thu, 21 Oct 2010 17:10:19 -0400

 My patch is IPv4/IPv6/DNS agnostic - it ought to work either way.  NFSv4  might be a \
problem due to the syntax differences in /etc/exports  (/etc/zfs/exports).

 All my patch does is use ';' as a special character to allow multiple  values (like \
you want) for each export.  Each value is prefixed by the  mount point and written to \
/etc/zfs/exports.


 I'm still running it - but it's for a home file server where I want to  restrict \
"root" access from certain VPNs.  Given that all it does is  change the output to \
/etc/zfs/exports, which is handled by the regular  NFS export mechanism, I don't \
think that there should be any significant  difference between home and \
production/enterprise use - unless NFS  exports keel over when there's hundreds of \
mount points (easy to do with  ZFS) rather than tens.  My home set up is exporting \
only 25 mount  points.
