does this mean i'm in deep doodoo?
like it, but maybe all is not lost.
should give output something like this:
Filesystem Type Size Used Avail Use% Mounted on
/dev/hda6 ext3 30G 18G 11G 62% /
varrun tmpfs 506M 108K 506M 1% /var/run
varlock tmpfs 506M 4.0K 506M 1% /var/lock
udev tmpfs 506M 132K 506M 1% /dev
devshm tmpfs 506M 0 506M 0% /dev/shm
lrm tmpfs 506M 19M 487M 4% /lib/modules/2.6.15-28-386/volatile
Note that I have something (/dev/hda6) mounted as root (/)).
You do not, yet you can get to a command line (for which you must have root mounted!).
So please try df -hT
again, and post all
If you still get nowhere, you'll probably have to reinstall, but make very sure you do not reformat your home partition. If you have important data on your home partition, I'd recommend you boot from a live CD, and copy your home files to an external disk before you start touching anything.
