My /home is also on a separate filesystem, so in principle I don’t like to mounting data under there, because then I cannot unmount /home (e.g. for fsck purposes) unless I unmount also all the other filesystems there. I keep all my filesystems on LVM.

So I just mount to /mnt and use symlinks.

Exception: sshfs I often mount to home.

But how many use it for browsing, which I imagine this data is from?

Am I to understand correctly that if you are running Gtk+ apps in the Gnome compositor, you get this working, but if you are running non-Gnome compositor with Gtk+ apps, it will not work? Or is it independent of the compositor?
