The question is does it really matter to me? What is my workaround? Clearly I need to be able to make the copy on the upper layer. And it is ro= ot that must make that copy. The effective user id to decide if the VOP_CREATE= is allowed must be root, or whatever user did the mount_unionfs. Not the user accessing the file right now. The owner uid and gid should be exactly that from the lower layer. Not the = euid of the user accessing the file. I need to understand how this VOP_CREATE ultimately works.=20 Note that it seems to work right with the shadow directories. So that might= be a clue. --=20 You are receiving this mail because: You are the assignee for the bug.=
