EDIT: Marking this as solved, sorry for the noise: Arghhh, my rules where badly written and I blindly copied them from a different thread. I guess I'll keep this post in the hopes that it will be useful to someone. The rules that actually worked for me:
Code:

# cat /etc/polkit-1/rules.d/10-automount.rules
polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.udisks2.filesystem-mount" &&
        subject.user == "myuser") {
        return "yes";
    }
});


Hello, this problem has appeared in many threads in different disguises and I tried many of the solutions posted (reflected in this post below) but I still can't manage to get my system to aumount a usb stick.

My relevant use flags:
Code:

[ebuild   R    ] gnome-base/gvfs-1.20.2  USE="http systemd udev udisks -afp -archive -avahi -bluray -cdda -fuse -gnome-online-accounts -gphoto2 -gtk -ios -libsecret -mtp -samba {-test}"
[ebuild   R    ] sys-apps/systemd-212-r5:0/2  USE="acl filecaps firmware-loader gudev kmod pam policykit seccomp -audit -cryptsetup -doc -gcrypt -http -introspection (-kdbus) -lzma -python -qrcode (-selinux) (-ssl) {-test} -vanilla -xattr" PYTHON_SINGLE_TARGET="python2_7 -python3_2 -python3_3" PYTHON_TARGETS="python2_7 python3_3 -python3_2"
[ebuild   R    ] sys-fs/udisks-2.1.3:2  USE="gptfdisk systemd -cryptsetup -debug -introspection (-selinux)"


My rules
Code:

# cat /etc/polkit-1/rules.d/60-automount.rules
polkit.addAdminRule(function(action, subject) {
    return ["unix-group:wheel"];
});
polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.*")) {
       return polkit.Result.YES;
    }
});

My processes running
Code:
$ ps -aux | grep udisks
mariana   1855  0.0  0.1 273344  4464 ?        Sl   06:40   0:00 /usr/libexec/gvfs-udisks2-volume-monitor
root      1888  0.0  0.1 425840  5092 ?        Ssl  06:40   0:00 /usr/lib/udisks2/udisksd --no-debug
mariana   2119  0.0  0.0  10592   960 pts/0    S+   06:53   0:00 grep --colour=auto udisks

And anyway when I want to mount I am required to register as root:
Code:
$ udisksctl mount -b /dev/sr0
==== AUTHENTICATING FOR org.freedesktop.udisks2.filesystem-mount ===
Authentication is required to mount SanDisk Cruzer (/dev/sr0)
Authenticating as: root
Password:

What do I need to do?

Hi.. I got a similar situation as yours.

After I have done trials and errors for a day, I figure out a way to have pcmanfm performing automount, unmount and eject.

First, I follow the first post from ssuominen in this link https://forums.gentoo.org/viewtopic-t-858965.html

Then, wiki "polkit" gentoo.
https://wiki.gentoo.org/wiki/Polkit
From that wiki link, it said the rule actions can be found in
Code:

 /usr/share/polkit-1/actions


Here is the one which works for me:
At
Code:
 /etc/polkit-1/rules.d/

create a file:10-udisks.rules

Code:

polkit.addRule(function(action, subject) {
    if (( action.id == "org.freedesktop.udisks2.filesystem-mount" ||
    action.id == "org.freedesktop.udisks2.filesystem-mount-system" ||
    action.id == "org.freedesktop.udisks2.filesystem-unmount-others" ||
    action.id == "org.freedesktop.udisks2.eject-media-system" ||
    action.id == "org.freedesktop.udisks2.eject-media") &&
         subject.user == "ewo" ) {
        return "yes";
    }

});


**Replace "ewo" with your username.

That code lets you automount, unmount, and eject usb drives and cds.
Note: If you eject usb drive from pcmanfm, pcmanfm quits by itself. It's a known bug that I don't know how to fix.

After I made the rule files,

I added "ck-launch-session" and "dbus-launch" on the line that executes the window manger in ~/.xinitrc file.

My example is for pekwm window manager.
Code:
 exec ck-launch-session dbus-launch pekwm


Lastly, make sure pcmanfm doesn't executed with ck-launch-session and dbus-launch. So, simply type:

Code:
 pcmanfm

to run pcmanfm from shell console like xterm.
Otherwise, the rules do not work with pcmanfm.

Hopefully, what I posted here can help you.
