Rick, I don't understand your reasoning here. What I see is that gvfs can do something when the real libsystemd0 is installed that it can't do without libsystemd0 - that is, it shows removable drives on the desktop. The presence of systemd itself is not required for this - it's not installed. Gnome probably has nothing at all to do with this. The only gnome packages installed here are gnome-accessibility-themes, gnome-icons, libgnome-keyring and libsoup-gnome. I'm running xfce desktop. The next experiment I did was to chmod -R 000 /lib/systemd/. I'm running this on a live-usb, so I can't reboot without losing changes. I tried restarting udev and dbus one at a time, and additional usb drives still show up on the desktop. Tried logging out of the desktop and back in, and the drives still show up. Then I dropped to runlevel 1 and then went back to 2 and got to the desktop. The removalble drives stopped showing up on the desktop. I don't know what had to restart to make the permission changes take effect. One odd thing: Fixed drives that are not in fstab show up on the desktop. This was not affected by the change in permissions on /lib/systemd, but it did depend on the presence of the real libsystemd0. Those drives don't show up on the desktop with the dummy libsystemd0 package. I tried reading the source code for libsystemd0, but I don't read C, so I got nothing out of it. -fsr _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
