my entire /usr directory and /home partition were replaced with symlinks

Asked by Luke Faraone on 2007-11-15

I was just running my OS normaly yesterday, when I started to be unable to launch applications.
I rebooted, and then got the error "too many levels of symlinks" while I booted.
Nothing starts but recoverymode, and then I can not run any non-built-into-bash commands.
Attached will be the output from ls -l of my /

I don't know what happened, but it would be useful if you could post the result of `mount`, `cat /proc/partitions` and `cat /etc/fstab`

Uh, I am running from a live cd, since I cannot boot properly, but here is what I get:

oops, wrong button

zimbatm (zimbatm) said : #5

Hmm. So the "ls -l" was also generated from the livecd ? In the fact is was "ls -l /media/disk-1/etc/fstab" ?

Luke Faraone (lfaraone) said : #6

I just reinstalled.
