Got one bad bit of information from my previous post. The problem DOES exist when just performing a pkg_deinstall. Apparently the one test I based my earlier post on wasn't repeatable. The problem is not with the portupgrade script itself. Dug in quite a bit further with this today. When pkg_deinstall calls to pkg_delete a .nfs file is created which is showing as being actively accessed by the ruby process. This file vanishes once pkg_deinstall quits. Due to that file, even attempting a "rm -rf" on that directory will fail within pkg_deinstall. For testing this out, we added a cheap hack to the portupgrade script immediately after the call to pkg_deinstall that just removes the directory once pkg_deinstall has ended. This works, but has no logic or error checking at this point. The pkg_deinstall script does not report that it didn't complete, so the main portupgrade script just keeps on going as though there were no errors. With that being said, what I believe needs to happen in the short term is to have a check within the portupgrade script where if the pkg_deinstall returns successful and the /var/db/pkg directory still exists, delete it. This would be right around line 1721. Obviously the more correct thing to do here would be to correct pkg_deinstall's behavior. That looks like it may be quite a bit more clever to do, thus my recommendation for fixing portupgrade now, and revisit pkg_deinstall later. I'm just concerned that the real problem may have more to do with the ruby engine and NFS than this script, which may take many months to correct.
