CentOS - Jun 2015 - Native ZFS on Linux

All that matters for CentOS is:

1: Red Hat doesn't ship ZFS because of Red Hat's lawyers'
interpretation
   of GPL+CDDL
2: Arguing about it here will not change #1
3: CentOS ships a clone of Red Hat Enterprise Linux and so won't have
   things that Red Hat's lawyers don't approve (see #2)

Please let it go.  I think everybody here knows your opinion.

As this is something that was never backed up with facts, it must be seen as 
pure speculation.

If you like to be taken seriously, come up with arguments from these lawyers...

Everybody here knows the anti OSS opinion of some RedHat people. 

Note that it is a well known fact that there has been never a verifyable 
explanation on why there should be a problem. We thus need to see everything 
against the explained usability as no more than disinformation politics.

On the other side: as long as this disinformation politics continues, Linux 
distros push temselves into a big disatvantage compared to platforms that ship 
ZFS.

This is a ludicrously absurd argument.
  a) ZFS is not included by RH.
  b) RH has some reason for this: either
      i) they like btrfs better, or
      ii) their lawyers like ZFS less.

In either case, UPSTREAM DOES NOT INCLUDE IT WITH THEIR ENTERPRISE OS.
Therefore, given CentOS's mission, this argument is "all sound and
fury,
signifying nothing".

I think that you need to simplify #1 to:

1: Red Hat doesn't ship ZFS

As that is really all that matters and so that people can't argue that you  
are making a statement of knowledge about what/why Red Hat's lawyers have  
decided.  It does not matter on these lists WHY they don't ship it, just  
that they don't.

Just my opinion.

According to https://access.redhat.com/solutions/79633 :

There's a lot of "I Am not a lawyer, but..." discussion in the
comments, but I think this is the best answer from Red Hat as to why
they don't ship ZFS.

+1

I for one will go with Btrfs. This is where the action is at, ATM, and more
and more companies are investing in BTRFS and going with it: SUSE, Fujitsu,
Docker, Facebook, Oracle...

///
Btrfs 1.0, with finalized on-disk format, was originally slated for a
late-2008 release,[12] <http://en.wikipedia.org/wiki/Btrfs#cite_note-12>
and was finally accepted into the Linux kernel mainline
<http://en.wikipedia.org/wiki/Linux_kernel_mainline> in 2009.[13]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-13> Several Linux
distributions <http://en.wikipedia.org/wiki/Linux_distribution> began
offering Btrfs as an experimental choice of root file system
<http://en.wikipedia.org/wiki/Root_file_system> during installation.[14]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-14>[15]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-15>[16]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-16> In summer 2012, several
Linux distributions moved Btrfs from experimental to production or
supported status.[17]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-17>[18]
<http://en.wikipedia.org/wiki/Btrfs#cite_note-18>
////

The ZFS Zealots (ZZ or Z-square) brigade act like kids on a temper trantum
because they preferred toy was left out of the playground. Please get down
your crying and yelling, there's people trying to work here (with btrfs).
;-p
