I'd like to mount a directory I have no control over (think NFS, or
floppy, ...) with clearly defined rights - like root:<some group>,
mode 0550 for all directories, and 0440 for all files. (Here I want
to have full *read* control, regardless of the original permissions).
[ I know that this special case can be (mostly) done by a read-only
binding mount; the part that is missing is eg. files with a
different owner being 0700. ]
I know that something like this is possible for eg. VFAT, which has
no right descriptors for itself; but I'd need that for arbitrary
directory trees, who themselves *have* permissions set.
Is there some way to achieve that?
Not at the moment, unfortunately. I suspect that with the recent
developments in user container support and/or overlay mounting it
will become possible to either write a UID/GID-translation overlay
filesystem or grant cross-UID-container keys to achieve what you
want. On the other hand that probably won't fully happen for up to a
year or so.
