No help from B.G.O. yet and I'm wondering if I should update libgdu to
see if that fixes it.  Is libgdu the same thing as gnome-disk-utility?
 If so, the latest version is 3.9.0 compared to 3.0.2 in portage:

https://git.gnome.org/browse/gnome-disk-utility/

Alternatively, should I try hacking the ebuild to unmask the udisks USE flag?
