mount, vfat and fmask

[ST <smntov@gmail.com>]

Hi,

I have to deal with users who use vfat on their usb sticks. I mount them
with certain fmask and all files get certain permissions. Once the media
is mounted I have to go through all files and change the permission of
some files if they fulfill certain conditions. chmod doesn't work in
this case.

1. Do you have any ideas for a workaround?
2. Is it possible to achieve this somehow with sudo?
3. Is there a program that creates some kind of virtual layer and
emulates extX filesystem above vfat?
4. If there is no other way but to change the source code of mount(or
something else?) what are the places in the code I have to take look on?

Thank you very much in advance
Sim

the subscriber to guess the address? Or is it a kind of IQ test to
filter out those who is not eligible to use the list? :)
