tramp 2.1.13-pre messed up symbolic link?

[Yang Zhang]

Hi all,

I discovered a problem with tramp. Basically I am using emacs 
23.0.60.1 on my Ubuntu 8.04 Linux machine (with kernel version 
2.6.24-19-generic) with the pre-installed tramp package 2.1.13-pre. I use 
this to edit files on a remote machine (running Solaris 10).

Tramp seemed to have messed up the symbolic links. For example, on the 
remote machine, I have:

test.txt (a normal file)
test_link.txt -> test.txt (a symbolic link to test.txt)

I use my local emacs to open the "test_link.txt" through tramp. Opening 
was fine. But any editing and saving would mess things up. After saving 
changes, the files became:

test.txt is unchanged,
test_link.txt became a normal file and no longer a symbolic link
test_link.txt~ became a symbolic link points to test.txt

A while back, I posted an article here that the emacs on windows vista 
with tramp had the exact problem. At that time, the conclusion was that 
windows does not support unix symbolic link. But this time, it happened to 
my Linux machine, weird??

Anyone have any idea and thoughts?

Thanks
