ZFS Boot Support Binding Change [PSARC/2008/301 Self Review]

[Octave Orgeron]

Hi,

I'm surprised that ZFS is not POSIX or UNIX compliant. Considering that many commercial customers and ISVs depend on compliance to the standards, I would think it's important to remediate the issues to prevent a possible show-stoppers. How much effort is required to fix these issues?

Given that ZFS does not yet conform to POSIX and UNIX standards
requirements (even though the zfs(1M) man page says that ZFS provides a
"standard POSIX file system"), that Solaris 8, 9, and 10 and their
updates are covered by several UNIX branding licenses, and that
(according to PSARC 2006/370) it is not possible to go back to a UFS
root after upgrading to a ZFS root, I STRONGLY object to allowing a
patch binding for this case unless a TCR is attached saying that this
feature can't be patched into earlier releases until all POSIX and UNIX
standards conformance bugs have been fixed.

I'm sorry that this information is not available outside of Sun, but
for those inside Sun, the heading "for ZFS:" on web page
http://stds-test.sfbay/resources/brand_status.html can be used as a
guide to known ZFS standards conformance bugs.

The fact that ZFS was granted a conformance waiver to be integrated
into the ON-NV gate before it passed the test suites (with a promise
that the bugs would be fixed before Nevada is released) can't be used
as a waiver for branded products that are already shipping.  Sun has
certified to The Open Group and many of our enterprise customers that
Solaris 8 and its updates, Solaris 9 and its updates, and Solaris 10
and its updates (current and future) do and will continue to conform to
UNIX branding requirements.
