Package: thunar Version: 1.6.3-2 or 1.6.11-1 Package: libglib2.0-0 Version: 2.50.3-2
I can confirm similar behavior of Thunar on my test system. The system has encrypted disk using dm-crypt and LVM (3 LVM volumes in 1 volume group on the encrypted disk and an unencrypted boot partition).
When I use Thunar as root it now shows the boot partition and LVM volumes in devices (in the Shortcuts Side Pane - on my system showing removable devices on desktop is disabled). These are all the entries from /etc/fstab on that system (with the exception of the swap entry).
This started after I recently upgraded some packages to testing/unstable versions. By downgrading packages back to stable (Jessie) versions I found that the problem is caused by upgrading the libglib2.0-0 from version 2.42.1-1 in stable to version 2.50.3-2 in testing/unstable.
I also tested it with different versions of thunar (stable 1.6.3-2 and testing/unstable 1.6.11-1) and the behavior was always the same as described above (complete upgrade of the test system from stable to testing also did not change the described behavior).
I suggest that showing all the entries from /etc/fstab (LVM volumes, etc.) is disabled as with the stable version, because it just adds clutter in file manager's GUI and could confuse the user to even accidentally unmount the volume. I was able to unmount the boot volume while the attempt to unmount the home and root volumes failed with error describing that the volume is in use.
By the way adding "comment=x-gvfs-hide" or "x-gvfs-hide" options to fstab entries is not working for me. The only way I found for hiding these devices is to hide them using the right click context menu in the Thunar Shortcuts Side Pane. This adds <property name="hidden-devices" type="array">...</property> to "~/.config/xfce4/xfconf/xfce-perchannel-xml/thunar.xml". But since sometimes UUIDs are used, it is very difficult to create a general config for multiple systems. Can any one explain what device ID types can be used in the "hidden-devices" property in "thunar.xml" or what options to add to fstab entries to hide them from devices in Thunar?
