That may be the case -- but what is the likelihood there would be code from that effort we would want? Vs. the real brain-share of DTrace which commits into Illumos?

I don't disagree in principle, but I feel it should have been an 'svn rename' not 'svn copy'. You didn't suggest or comment on the SCM operations having two "vendors" puts us in. I don't think you can make precise statements about an illumos vendor branch without considering those. > Concerning ZFS: the main developer of the encryption stuff > did stay at Oracle.

We can always figure out something *if* it comes to pass that there is a code drop from Oracle that we want to consume. I believe the question which code base are we *most likely* to pull technology from.

That misses my point. Yes, copying is a very cheap operation in SVN. (so is 'svn rename') The issue is should we have _two_ vendors that we are attempting to merge into the same files within HEAD? -- -- David (obrien@FreeBSD.org)
