I'm confused why devpipe allows wstat. The roundabout way is more general, checking read/write permissions as well. The permission info should line up with how a dev allows permissions, and making open dependent on what the mode is actually set to would make the info and the behavior always line up. It might be as easy as a bitwise or. I'll hack up something later tonight. If we don't decide on that route, then devpipe should disallow wstat. >RFNOMNT does not remove access to #|, #d, #e, #c, or #p That's what I get for only reading the man page without testing. Thanks, Amavect
