Example: we use unionfs for our diskless gentoo client project: on the client side, because we want a ro-exported nfs-root. And on the nfs-server side to maintain different client configurations. So, we have a union of unionfs (with nfs in between). Sometimes ago I posted a possible solution to this problem, where I suggested to use a sort of layer-id as an additional prefix for the whiteouts. I think, this would be a nice extension to unionfs. But the unionfs-team is concentrated getting unionfs into the main-line kernel - and clearly this should the first goal. To solve our problem, I wrote and posted a patch to prevent the lookup of whiteouts in the rightmost ro-branch, which we use as our ro-nfs-root. -- Wilhelm Meier _______________________________________________ unionfs mailing list [email protected] http://www.fsl.cs.sunysb.edu/mailman/listinfo/unionfs
