>Description:
"zfs set" write a wrong entry in "etc/zfs/exports" when the command contains a "-" character in the hostname.
>How-To-Repeat:
--------------------------------------------------------------------
root at XXX ~ # zfs set sharenfs="-maproot=root xxxxxx-01" tank/nfs
--------------------------------------------------------------------

--------------------------------------------------------------------
root at XXX ~ # cat /etc/zfs/exports
# !!! DO NOT EDIT THIS FILE MANUALLY !!!
/nfs    -maproot=root xxxxxx 01 
--------------------------------------------------------------------

--------------------------------------------------------------------
root at XXX ~ # showmount -e
Exports list on localhost:
--------------------------------------------------------------------

>Fix:
Complement the "-" character manually into the "etc/zfs/exports" file.

--------------------------------------------------------------------
root at XXX ~ # cat /etc/zfs/exports
# !!! DO NOT EDIT THIS FILE MANUALLY !!!
/nfs    -maproot=root xxxxxx-01
--------------------------------------------------------------------

--------------------------------------------------------------------
root at XXX ~ # service mountd reload
--------------------------------------------------------------------

--------------------------------------------------------------------
root at XXX ~ # showmount -e
Exports list on localhost:
/nfs                               xxxxxx-01
