This includes the changes to the file system. Also, the BSDish features of HP-UX do not share code with the SYSV features. It's like two OS's in one. I have no first hand knowledge of this (I'm just a user), just passing along rumors. Sorry this is off the subject, but HP-UX is a hot-button for me. Ron Steele
