[HOWTO] Mount devices by users without password

[magia]

To allow users to mount devices (e.g. another partition of internal drive) without authentication, create /etc/polkit-1/rules.d/99-allow-mount.rules with these lines:

Code: Select all

// Allow all users to mount devices without authentication
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-mount")) {
      return polkit.Result.YES;
   }
});
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-mount-system")) {
      return polkit.Result.YES;
   }
});


Note: This howto is added to the Mageia Wiki.

Hi all,
i had some errors using xfce4 to mount and unmount usb media. Sometimes i haven't any error message, other time i had permissions errors.
I solved creating an udev rules /etc/polkit-1/rules.d/10-drives.rules as follow:

Code: Select all

// Allow all users to mount devices without authentication
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-mount")) {
      return polkit.Result.YES;
   }
});

polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-mount-system")) {
      return polkit.Result.YES;
   }
});

// Allow to unmount
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-unmount-others")) {
      return polkit.Result.YES;
   }
});

// Allow to eject
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.eject-media")) {
      return polkit.Result.YES;
   }
});

polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.eject-media-system")) {
      return polkit.Result.YES;
   }
});

polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.eject-media-other-seat")) {
      return polkit.Result.YES;
   }
});


bye

Under MGA3(64) I experience the same problem.
I created the proposed file. It enables Users to mount partitions on internal drives.
But USB-Sticks are not shown in Thunar.
They are recognised by the system:

Code: Select all

Well, if they're not shown at all, that's not the same as shown, but not mountable as user without password, no?
Maybe some polkit stuff missing, or maybe thunar hasn't been updated for udisks2 "goodness" ...

OK I'll start a new thread in the german forum.

EDIT: Problem solved. Filesystem in USB-stick was defect.
