Interesting.
I admit I don=E2=80=99t use NFS v4.
Is it much faster than NFS v3 these days?
But I=E2=80=99ve always added the line from exports(5) into the sharenfs =
property like
zfs get sharenfs datapool/nfs/ds3-documents
NAME PROPERTY VALUE =
SOURCE
datapool/nfs/ds3-documents sharenfs -maproot=3D1003 -network =
10.10.10.0 -mask 255.255.255.0 inherited from datapool/nfs
These lines get written into /etc/zfs/exports
I like it that way because if a filesystem is destroyed, I don=E2=80=99t =
have to remember removing it from /etc/exports.
I also admit I=E2=80=99m heavily influenced by Solaris on this =
particular setting=E2=80=A6
