Description of problem:
symbolic links on NFS shares became "corrupted" (preferably became hard links)

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. create a file  on a NFS share : let's say "toto"
2. link it to "totolien" : ln -s toto totolien
3. move toto to toto-old : mv toto toto-old 
 ls -l totolien : it's a broken link : everything is ok
4. recrate toto : touch toto
 ls -l totolien : it points to the new toto : everything is ok
5. restart the station
6. do a "ls -l"



2. move it (so the link is broken
3.
  

Actual Results:  "totolien" points to "toto-old" (as I created a hard link)

Expected Results:  "totolien" should point to the new "toto" file

Additional info:

It appears always in this case :
Our gnome environment is installed on a NFS share on a solaris 2.9 server.
All stations automounts read-only (except mine) /opt/gnome
When I upgrade a gnome applications ( gnomecanvas this morning), I did
cd /opt/gnome/lib
mv libgnomecanvas-2.so.0.1000.0 libgnomecanvas-2.so.0.1000.0-OLD (I have to avoid deleted open file on all stations)
Here libgnomecanvas.so.1 become a dead link
Then i do a typical : ./configure --prefix=/opt/gnome && make && make install
libgnomecanvas-2.so.1 is no more a dead link and points now  to libgnomecanvas-2.so.0.1000.1 
Everything is fine.

In my stations , i do a "lsof|grep libgnomecanvas-2"
I have libgnomecanvas-2.so.0.1000.0-OLD : normal
I restart my session (not my stations)
I have now lsof|grep libgnomecanvas-2 : libgnomecanvas-2.so.0.1000.1

then I restart my station (so I flush all nfs caching).
lsof|grep canvas gives libgnomecanvas-2.so.0.1000.0-OLD : oooppss!
ls -l /opt/gnome/libgnomecanvas-2.so.1 points to libgnomecanvas-2.so.0.1000.0-OLD


I don't know where the troubles come from : 
Solaris 2.9 bug ? I doubt
gnome recreating links ? I doubt too

So I really things it's a NFS/Kernel/Fedora bug.
