Public bug reported:

I have a ZFS On Linux setup as my main backup/fileserver that uses
RaidZ1 (similar to raid 5: 3 disks, 1 parity).  Because Linux doesn't
show the free space correctly for the complete disk/mount point, the
disk space indicator on my Windows machine for this share gives the
wrong info. The solution in Samba 3 / Ubuntu 13.10 was to add a "dfree
command = scriptname" configuration option to smb.cnf that knew how to
figure out the correct disk space/usage. This was all working and the
total disk space was displayed correctly in Windows Explorer on the
client.

However, now after upgrading to 14.04, the diskspace suddenly gets
displayed all wrong again.  I checked the script (it worked ok) and even
let it output "0 0" to see if it actually gets called by samba, but
nothing changed on the indicator of my windows machine. I did reboots of
the server, and the client, and nothing changed. I also changed the
"dfree command" to a invalid scriptname, and moved it from global to a
share section. Nothing worked.

Testparm gives no errors, so it looks like samba somehow just ignores
this parameter. Manpage for smb.conf shows that the "dfree command"
option is available.

Looks like a regression to me, and is frustrating, because I can't see
how much space I am using on my fileserver.
