A previously mounted share (Pre 0.6) had a
Description with a full stop (aka period) in it.
FreeNAS 0.6 will not permit this, and gives an error
when trying to save the mount again say, after
modifying the Share Name or Description.
Also Share Name can be SAVED with a space in it
(like - Share Name) and gives not error, but then
gives ERROR - retry when Applying Changes with no
reason for the Error.
Validation for correct formatting, if required,
should happen at Save step with indication that the
space chr is not permitted.
