Yes, in many cases. However, those of us managing Usenet spools spread over half a dozen disks would probably not mind (I'm not particularly fond of newfs'ing an entire spool after a single disk crash, but it might be an acceptable tradeoff). It would be nice to see some sort of solution, even if it's not necessarily "optimal" at this time. :-) ... JG
