You can not change the directory flag with chmod, only the permission
bits.*

@creatxr: Let me make a little search in my info sources; I remember
having seen something related some time or other but I don't remember
whether it can be done or not--although I think it can.


* In case there is any doubt:
Quote from: man chmod[... discussion of UGO-RWXS options omitted ...]

A numeric mode is from one to four octal digits (0-7), derived by
adding up  bits  with  values 4, 2, and 1.  Omitted digits are assumed
to be leading zeros.The first digit selects the set user ID (4) and
set group ID (2), and  restricted deletion or sticky (1)
attributes.The second digit selects permissions for the user who owns
the file: read (4), write (2), and execute (1);The third  selects
permissions  for  other users in the file's group, with the same
values; andthe fourth for other users not in the file's group, with
the same values.[...etc...]

Note that you can afaik open directories as files using normal FPC
I/O.

I don't know if the URL still works but I found a "note to myself"
about this:

Changing the inode type would give you a corrupt filesystem, nothing
else. (You would do that with filesystem debugging tools, which are
filesystem specific and pretty dangerous - backup what you can before
attempting anything like that. Example for the Linux ext filesystems:
debugfs.)
