I am using Linux Mandriva 2007 and whenever I plug in my USB drive (NTFS formatted) the "KDE Media assistant" (don't know the real name for the pop-up screen) asks me what I want to do with it. Clicking the "open" option does actually mount it, but only with read/execute rights for root.

[tsd@bobby ~]$ ls -la /mnt/
total 11
drwxr-xr-x  5 root root 1024 Nov 11 22:05 ./
drwxr-xr-x 24 root root 1024 Nov 11 21:41 ../
drwxr-xr-x  2 root root 1024 Oct 29 20:50 cdrom/
dr-x------  1 root root 4096 Oct 29 18:57 TSD-BACKUP/
dr-xr-xr-x  1 root root 4096 Nov  3 19:59 windows/
[tsd@bobby ~]$
However, looking in mtab gives me this:

/dev/hda1 /mnt/windows ntfs ro,umask=0,nls=utf8 0 0
/dev/hda7 /storage ext3 rw 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
/dev/sda1 /mnt/TSD-BACKUP ntfs rw,noexec,nosuid,nodev,sync 0 0
having a look into the respective rule for udev shows me this:

# usbfs-like devices
SUBSYSTEM=="usb_device", PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", NAME="%c"
# libusb device access (mount usbfs or usbdev nodes)
DEVPATH=="/module/usbcore", ACTION=="add", \
              RUN+="/bin/sh -c 'sleep 1; /bin/mount -t usbfs -o devmode=0664,devgid=43 none /proc/bus/usb'"
My question now is: Who or what does automatically write the mtab file here?

I would like to change it so that group and others have the rights to read and execute the volume "TSD-BACKUP" too.
