- Uh, I *really* don't think so. There are no processes using /CD, and
- only the one process using /dev/ptyra. Either that, or else pff is
- totally hosed, and I don't think that's the case. Even if it were...

- I *did* try this. I created a brand-new, empty directory. I remembered
- not to cd into the new directory (1/2 :-). I tried to mount /dev/rz5c on
- the new directory. No go.
-
- On the other hand...

- Now *that* is news to me, but then as I mentioned in a previous post, I
- make no pretensions toward being a kernel hacker.
-
- It may be that pff incorrectly assumes that any two devices with
- identical major and minor numbers are necessarily the same device. *I*
- certainly thought so :-)
-
- I notice that ofiles (which I didn't run yesterday) reports that nobody
- is using /dev/rz5c, even though pff still finds the telnet process on
- ptyra.
-
- So what's left? I still think that "recycling" major and minor numbers
- is a particularly strange thing to do, but if it really has no bearing
- on my case, what does?
-
- It's definitely not that the mount point directory is busy. I can't
- find any other processes using the "real" /dev/rz5c. So why won't
- mount do what I want it to do?
-
- HELP!!!
