ZFS and 'traditional' nfs-export

[Arno J. Klaassen]

Hello,

I googled a bit on this question but could not find
a clear answer :

is there any risk/inconvenience/advantage in exporting
a ZFS-fs by just putting it in /etc/exports the old
way and leaving the 'sharenfs' option on the filesystem off?

I'd like to replace a UFS-based server serving mostly
linux-clients which work well now with a ZFS-fs, and somehow
am a bit waterfearing changing the nfsèoptions which worked
great till now.

Thank you in advance,

regards, Arno
