I do not know the command line for symbolic links. I created the symbolic link of /Centos/5 to /Centos/5.1 in Nautilus which does not have a method of changing a symbolic link. Only deleting it and creating a new one.
Is there a command line to change /Centos/5 to link to /Centos/5.2 ?
IMNSHO, anyone that has more than 2 Centos boxes should maintain their own local repo. Of course it only took me a few years until I got mine up and running! Just had some challenges walking the talk :)

Not that I know of, I always just delete an recreate it using "rm -f" and "ln -s" at the command line.

I just delete and re-create it

I agree with this when maintaining more than a couple boxes, certainly if maintaining more than 4 or 5 at the same location, especially with limited bandwidth.

It used to be that the -f worked. Sometime in the past that disappeared. Bad decision, IMHO.

It's still there:
nox:~/tmp/ln$ touch foo nox:~/tmp/ln$ touch bar nox:~/tmp/ln$ ln -s foo baz nox:~/tmp/ln$ ll total 12 -rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 bar lrwxrwxrwx 1 gavin gavin 3 Jun 26 10:06 baz -> foo -rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 foo nox:~/tmp/ln$ ln -sf bar baz nox:~/tmp/ln$ ll total 12 -rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 bar lrwxrwxrwx 1 gavin gavin 3 Jun 26 10:06 baz -> bar -rw-r--r-- 1 gavin gavin 0 Jun 26 10:06 foo
It does seem to be flaky though. I definitely have had times it hasn't worked recently.
Cheers, Gavin

If there's already a link to a directory, you need -n (usually);
-n, --no-dereference treat destination that is a symlink to a directory as if it were a normal file
Otherwise, you'll end up with a rogue link inside the existing directory:
mikaelf@mikaelf:/tmp/ln$ ln -sf foo link mikaelf@mikaelf:/tmp/ln$ ls -lR .: total 8 drwxr-xr-x 2 mikaelf mikaelf 4096 2008-06-26 11:19 bar drwxr-xr-x 2 mikaelf mikaelf 4096 2008-06-26 11:16 foo lrwxrwxrwx 1 mikaelf mikaelf 3 2008-06-26 11:19 link -> bar
./bar: total 0 lrwxrwxrwx 1 mikaelf mikaelf 3 2008-06-26 11:19 foo -> foo
./foo: total 0
