Well i did a forced fsck on all my filesystems and now a bunch of files are
corrupted/missing in /usr so rather than figuring out which file is missing
and which package to reinstall i'll reinstall the whole system ( will be much
faster in my opinion ).

I did a fsck ( not forced ) then bootedup 2.4.16 and had the problem , then i
tried to compile 2.4.14 on the machine and it failed ( because of the symlink
problems ) , i compiled the kernel on another machine, installed it and
booted i had the same problem again. I then did the force fsck and booted
2.4.14 and it was fine. You might be right about 2.4.16 , i'll boot it again
and see if the problem is still there.
What's weird is that the fsck did not report any problem on my root partition
and i was seeing problem on it ...
The only problem it saw ( and fixed ) was in /home
