OK, sorry for the flood, but a final remark.

You can mount the actual (disk) root file system a second time, but just
read only. Example:

mount -t ext2 -r /dev/disk/by-label/ROOT_FS /mnt

After that, 'df' should show /mnt also being 100% full, but this time
you can see what the disk file system really looks like, under /mnt.
You won't be able to change it though, due to the read only mount.

But if you find stuff which eats up space excessively you can at least
proceed as said earlier, i.e. get rid of the tmpfs if necessary, remount
the root fs writable and then delete.

If 'du' still says ~600MB on /mnt though it could be the file system is
really corrupt, although that shouldn't be possible because it'd get
checked on boot. But, while / being mounted read only, you could try to
force a check anyway

e2fsck -f /dev/disk/by-label/ROOT_FS

see if that freed any space and best reboot afterwards.

OK, that's about all I got to say I guess ;)
