Two links to a directory?

[Michael Nolan]

Browsing around on my NCR Tower (SVR2) trying to solve a problem with lock
files not being deleted by uucico, I discovered that there appear to be two 
links to a directory, although I had thought that was not permitted in unix.  
(multiple file links, yes, but not multiple directory links)

(ls -ail /usr/spool)
total 8
 1935 drwxrwxr-x   7 root     rootgrp      160 Jun 24 15:42 .
   64 drwxr-xr-x  28 bin      bin          480 Mar  7 16:44 ..
 1936 drwxr-xr-x   4 root     sys           64 Jul 18  1988 cron
 1984 drwxrwxrwx  16 uucp     daemon       384 Jun 24 16:02 locks
 1942 drwxr-xr-x   8 lp       bin          320 Dec 27 17:09 lp
 1980 drwxrwxr-x   3 root     rootgrp      144 Feb 12  1990 lpd
 1984 drwxrwxrwx  16 uucp     daemon       384 Jun 24 16:02 uucp
 1997 drwxrwxrwx   2 uucp     daemon        96 May 25 03:37 uucppublic

Note that both locks and uucp have the same inode number.  As one might expect,
/usr/spool/locks and /usr/spool/uucp have identical contents.  If I create
a file in one, it shows up in the other.

Is this normal and, if not, is it a serious problem?  (Is it causing the 
LCK..tty07 file not to be deleted after an incoming uucico call?)
