FWIW, i think it's worse than you describe. for me: - it doesn't matter what layer i delete the files from - the files aren't open anymore the only way i found to recover disk space was to unmount the upper layer (which hung for a while, assuming writing the new disk contents), or, later reduce kern.maxvnodes. .mrg.
