Polkit rules for udisks, and udisks2. Compatible with udiskie and Dolphin.
// Original rules:
// Changes: Added org.freedesktop.udisks2.filesystem-mount-system, as this is used by Dolphin.
polkit.addRule(function(action, subject) {
var YES = polkit.Result.YES;
// NOTE: there must be a comma at the end of each line except for the last:
var permission = {
// required for udisks1:
"org.freedesktop.udisks.filesystem-mount": YES,
"org.freedesktop.udisks.luks-unlock": YES,
"": YES,
"": YES,
// required for udisks2:
"org.freedesktop.udisks2.filesystem-mount": YES,
"org.freedesktop.udisks2.encrypted-unlock": YES,
"org.freedesktop.udisks2.eject-media": YES,
"org.freedesktop.udisks2.power-off-drive": YES,
// Dolphin specific
"org.freedesktop.udisks2.filesystem-mount-system": YES,
// required for udisks2 if using udiskie from another seat (e.g. systemd):
"org.freedesktop.udisks2.filesystem-mount-other-seat": YES,
"org.freedesktop.udisks2.filesystem-unmount-others": YES,
"org.freedesktop.udisks2.encrypted-unlock-other-seat": YES,
"org.freedesktop.udisks2.eject-media-other-seat": YES,
"org.freedesktop.udisks2.power-off-drive-other-seat": YES
if (subject.isInGroup("storage")) {
return permission[];

Hey, looks like the filesystem-mount-system is just what I needed for Thunar too. Thanks for this! 👍

You can simplify this by using a "catch all" on org.freedesktop.udisks2. permissions like this:

polkit.addRule(function(action, subject) {
    if (subject.isInGroup("wheel")) {
        if ("org.freedesktop.udisks2.")) {
            return polkit.Result.YES;
