I have solved this by creating a group for each filesystem that don't
support access permissions. E.g I have a group "fat" with gid=23 for
fat disks. Then each user that should have write access to the disk
must be a member of that group. That you do be adding the line
fat::23:oz
to your /etc/group (see also manpage for adduser).
Then in your /etc/fstab you should use gid=23 and umask=002, this
means no matter who mounts the filesystem (probably root during boot)
all the files and dirs will have group 23 (fat). The umask option tells
the system to make no restrictions for owner and group (in which oz is
a member), that is all the files and dirs will get access permission
rwx for owner and group and rx for others.
The line in your /etc/fstab would look something like this:
/dev/hdxx /DOS vfat defaults,gid=23,umask=022,quiet 1 2
If you don't use the quiet option you will get an error message each
time you try to change the access permissions (done e.g. during moving
with mv)
Hopes this helps, it solved all my problems, and is a solution
that supports that some users have write permissions and others not.
(The ones that are members of fat have)
