Ok so I have my 2.6 kernel installed and booting just fine with grub. However, I can't seem to make the symbolic link between by 2.6 kernel directory (/usr/src/linux-2.6.0) and the /usr/src/linux directory. I was trying to emerge a package in gentoo and it said the kernel version was not determined. I was trying to make the link with ln -s but it said linux/linux-2.6.0 : file exists. Is there something else I am doing wrong? I still have my 2.4 kernel installed as well, because I am still testing things with 2.6 before I commit.

did you do it the wrong way? I mean, the command goes like this:

ln -s source_directory symlink_name

where source_directory is the dir you want to be linked (/usr/src/linux-2.6.0) and symlink_name is the name of the symlink you want to create (/usr/src/linux). the symlink_name component must not already be there, because if it does, it would be overwritten and that's not done. so if you did

ln -s /usr/src/linux /usr/src/linux-2.6.0

then you got the error because a dir called /usr/src/linux-2.6.0 already exists (but on the other hand, there is no - or at least should not be - a thing called /usr/src/linux). so, to get this correct:

1) if you already have a symlink called /usr/src/linux, remove it:

file /usr/src/linux
(now this should print a line like this -> XXX: symbolink link to 'YYY' and if it does, then it is a symlink and can safely be erased. if you get an error which tells you that there is no such thing as /usr/src/linux, just move on, over the next step)
rm /usr/src/linux

2) create the symlink to the 2.6.0 directory:

ln -s /usr/src/linux-2.6.0 /usr/src/linux

and you should be fine.

Ok, you were right that worked just fine. I didn't know that the /usr/src/linux shouldn't have already been there ... I actually created that directory and tried to link it, but what you said makes sense. As always thanks for the help!

heh, no problem

Ok. Now how is it done in the GUI, KDE or Gnome. Please and thank you.

Is anybodu knew how to chnage existing symbolic link?
i have created symbolic link
ln -s <folder> <link folder>
but now i want link another folder to the same link without using unlink command
currenty linkfolder->folder
then i tried ln -s <Another folder> <link folder>
so it should be linkfolder->Another folder
In short i want to override previous link
is there any command for that?
please let me know

I have read once something like

"ln -sf source new_link"

maybe this may help
