I'm back to play Banquo's ghost. This talk about syntax is all very well, but
does anyone have answers for questions like the following:
* Will
chmod u-rwx somefile; chmod u+rwx somefile
still work? What special-case behaviour will be needed to make it work?
* Will it be possible to make a attribute file the child of
/pub/some_ordinary_directory via a hard link? Will it be possible to make an
attribute file into an attribute file for some other file? That has completely
different permissions? And is owned by a different user? What will have to
happen, in either case, at the time the file is hard-linked to its new parent?
* What will prevent a supposedly unprivileged user from chowning a file to any
other user - for example, chowning a setuid binary to root?
Any takers?
