It won't work :) The challenge is exporting two shares from the same folder. Linux has a "bind" command which will make this work, but from what I can see there isn't an equivalent on OpenSolaris. This isn't a big deal though; I can make it work using CIFS. It isn't something that has to be NFS, but I thought I would ask to see if there was a simple solution I was missing. >>> I guess he has some application he can imprison into a specific >>> read-only subdirectory, while some other application should be able >>> to read/write or something like that, using the same username, on the same >machine. >> >> It is the same application, but for some functions it needs to use >> read-only access or it will modify the files when I don't want it to. > >Sounds like a simple dtrace script should do the trick, too. Unfortunately, there isn't anything I can do about the application, and it really isn't a big deal. There is a pretty straight forward workaround. Have a great day!
