zfs discuss - Aug 2007 - zfs -H output ??"s

Hi,

I have a customer that would like to open a RFE on the following issue...

Describe the problem:
 
It would be nice if zfs -H didn''t print any output to STDERR (or if 
there was some way to tell it not to).
 
Given it''s for scripting mode, I''m going to be checking the
return code
anyway and doing something based on the return code not the string sent 
to STDERR.
 
This will make scripting nicer as I don''t have to continuously send 
STDERR to /dev/null when doing things like checking for the existence of 
a filesystem.


Any ideas? I thought I would ask before creating the RFE.

Regards,
Dave

There must be dozens of ways of checking for the existence of a file
system besides zfs list.  mount comes to mind.
