For that i know the GNU Project is based on the GNU General Public
License (i suppose you are using GPLv3
http://www.gnu.org/licenses/gpl-3.0.txt for the kernel KFreeBSD) and
is easy to undestand why:

FreeBSD license   (#FreeBSD)

This is the original BSD license with the advertising clause and
another clause removed. (It is also sometimes called the “2-clause BSD
license”.) It is a simple, permissive non-copyleft free software
license, compatible with the GNU GPL.

If you want a simple, permissive non-copyleft free software license,
the FreeBSD license is a reasonable choice. However, please don't call
it a “BSD” or “BSD-style” license, because that is likely to cause
confusion which could lead to use of the flawed original BSD license.

Other Free Software Licenses compatible with the GNU General Public License

To the same time the license which supports the ZFS is in contrast
with the GNU General Public License:

Common Development and Distribution License (CDDL), version 1.0   (#CDDL)

This is a free software license. It has a copyleft with a scope that's
similar to the one in the Mozilla Public License, which makes it
incompatible with the GNU GPL. This means a module covered by the GPL
and a module covered by the CDDL cannot legally be linked together. We
urge you not to use the CDDL for this reason.

Also unfortunate in the CDDL is its use of the term “intellectual property”.

Sincerely i don't understand because you adopted ZFS until AdvFS
(Advanced File System, designed by Digital Equipment Corporation for
their Digital UNIX (now Tru64 UNIX) operating system.


AdvFS, also known as Tru64 UNIX Advanced File System, is a file system
developed in the late 1980s to mid 1990s [1] by Digital Equipment
Corporation for their OSF/1 version of the Unix operating system
(later Digital UNIX/Tru64 UNIX). In June 2008, it was released as open
source under the GNU GPL license[2].

You can find too anything i wrote in past on:

something was not proper correct, but other thing yes :-)

about AdvFS this is one good alternative to ZFS or is possible to use
LVM Logical Volume Manager


so why don't use one of these 2 ones ?

if i am in wrong, please correct me :-(

awaiting your reply,

happy hacking,

paolo del bene
