That is, let /dev/sd0s1 be a symlink > to /dev/sd0/slice1. Symlinks could also help the sd0a -> sd0s1a problem. but sd0a is a different thing to sd0s1a.. sd0a has a specific meaning.. it's shorthand for: sd0/partitonA where sd0s1a is shorthand for; sd0/slice1/partitionA they imply something. it's not that it is impossible, but that it breaks all the layering. you need to reach out of your layer to decide if you need to make the symlink. and you need to know things that your layer doesn't otherwise need to know about the insides of another layer. > > -Archie > > ___________________________________________________________________________ > Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com >
