Package: usbmount Version: 0.0.14 Severity: wishlist Tags: patch Hello,
here is a patch for /usr/share/usbmount/usbmount which allows _any_ user to unmount a device which was mounted automatically by usbmount. This is great for USB sticks which are formatted as vfat and which you do not want to mount with the "sync" option due to the resulting horrible write performance. You can safely use such USB sticks without "sync" if you always remember to unmount the device. With this patch, unmounting becomes very easy - for example, it can be done in a convenient way using Nautilus on the Gnome desktop. The idea is: Add to /etc/fstab entries of this form: /var/run/usbmount/dev-media-usb0 /media/usb0 auto users,noauto 0 0 /var/run/usbmount/dev-media-usb1 /media/usb1 auto users,noauto 0 0 Note how each device is the string "/var/run/usbmount/dev", followed by the mount point name (with "/" replaced by "-"). Next, have usbmount create symbolic links to the actual devices. For example, when mounting /dev/hdb4 on /media/usb0, first create a symlink /var/run/usbmount/dev-media-usb0 -> /dev/hdb4 and then mount /var/run/usbmount/dev-media-usb0 on /media/usb0. The symlink trick has the advantage that /etc/fstab does not need to be changed dynamically whenever a device is plugged in. Due to the "users" option in the fstab line, any user is allowed to unmount the device. The filesystem type ("auto" in the two lines above) is ignored by umount AFAICT, so it need not be correct. Another nice thing: The mount command actually notices that the mount device is a symlink _and follows it_, so mtab will still show "/dev/hdb4" as the device instead of /var/run/usbmount/dev-media-usb0! Cool! IMHO this is a very useful feature - hopefully it'll make its way into your package!
