The first and most important question is whether "/dev" is a real filesystem, or if it is a virtual (e.g. "tmpfs" type) filesystem on your machine? > --------------------- debugfs -------------------- > 3014659 (12) . 2 (12) .. 3014663 (12) fd 3014664 (16) mapper > 3014665 (12) pts 3014666 (12) shm 3014667 (16) agpgart > > > --------- from ls ----------- > autofs ecryptfs loop6 pts random sr0 > tty2 tty35 tty50 tty9 ttyS22 uinput vcsa2 > block fb0 loop7 ram0 rfkill stderr It would be useful to show "ls -li" information for some of the entries that appear via debugfs (e.g. "fd", "pts", and "shm" above), and also some of the entries that do not appear in debugfs.
