USE="gdu" enables sys-apps/gnome-disk-utility integration, but this is deprecated and USE="udisks" should be used instead. USE="gdu" is disabled since gvfs-1.18.3-r1. emerge world produces this output on arm: WARNING: One or more updates have been skipped due to a dependency conflict: gnome-base/gvfs:0 (gnome-base/gvfs-1.18.3-r1::gentoo, ebuild scheduled for merge) conflicts with >=gnome-base/gvfs-1.10.1:0[gdu] required by (mate-base/caja-1.8.1::gentoo, installed)
Created attachment 386732 [details, diff] New ebuild using udisks but not gdu.
I would like to confirm the existence of the bug and that the proposed ebuild solves it (on amd64).
For your convenience, you can find the ebuild in my overlay. layman -a hnaparst
