Looking at the output of your mount command, you have a lot of stuff there that looks like files (e.g. the DSCF stuff. I don’t get any of that:
/dev/root on / type ext3 (rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=40960k,mode=755)
tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=40960k)
