- But, this is exactly the kind of behaviour which I whined about to TGV. By
- using logical names, we can not only dismount and remount the NFS filesystem,
- we even moved one from a Unix box to the VMS system for performance reasons
- (the Unix box was 28 miles away).
-
- There is no (a small, easily swallowed word) reason for a user to be using hard
- coded device names. Your Unix types don't use /sd0h, they use /home/bear/user.
- So you can tote that puppy around as needed.
-
- Just my opinion, and we all know about opinions :-) (they other guy's stink)
