Re: Ten Reasons To *NOT* Use ZFS:

2 . ZFS does not support the necessary extended attributes and ACLs to enable the implementation of SELinux security. Instead Sun prefers the

deployment of its own security software "Trusted Solaris", which is

not FOSS and runs at a cost of "$995 per seat for the Standard Edition

Desktop System to $79,495 for the Certified Edition Data Center
Server."

The part with the necessary extended attributes and ACLs is bull. The

reason is simple. It supports ACLs and it supports extended attributes,

it's just a matter of using that support in the Linux port, and
mapping-it to the corresponding Linux API. Since we have no real Linux

port yet, we have no acl and xattr. There are some filesystems that come

to mind right now that are available on Linux and still don't support
xattr and acl "the Linux way" (ReiserFS ring any bells?).
Going on to the second part: it's bull. Most of the Trusted Solaris

extensions have already been moved to OpenSolaris and Solaris 10, others

will follow. Sun is working hard to move the Trusted Extensions that
they had in their CDE desktop to GNOME. This seems like open-source to
me, and if we have open-source, you won't have to pay the $995-$79495
for the product.. The whole pricing is completely irelevant, as

OpenSolaris is still to have it's first release (Solaris 11, in the Sun versioning). It's just like comparing the Fedora Core 0.9x releases with

RedHat 9. There were a lot of voices in those days that accused RedHat
of abandoning the community. Now Fedora Core has an even stronger
community than RedHat Linux ever dreamed of having.
