Well, yes it is.

[root /]# ls -od tauceti 
drwxrwxrwx    8 root         4096 Mar 10 21:27 tauceti
[root /]# ls tauceti/

Way back when I was first messing with Unix, this bit me. I don't remember
the circumstances, but the partition wasn't mounted, and I damn well knew
those files were there. To top it off, I'd also managed to create a new
subdirectory with files there. For a better example, I shouldn't have
removed the file before remounting the filesystem -- would have made a
better example, because the file would appear to be gone after the mount.

Actually, I still think this is just a little wierd. I mean, it makes
sense that there has to be a directory entry in / (or wherever) for the
mount point. But it would be nifty if it were flagged as a "mount point"
entry, instead of being a real directory.
