Yes, that message would be very indicative :-) As that partition is still unused I did an experiment. I formatted it again as XFS, destroying the encryption, with gparted. Instantly it appeared mounted in the desktop. I tried to apply a label to it and failed, because it was mounted. So I mount it, label it, and again instantly, the device is again mounted on the desktop - this morning I can see the display. I have now disabled this action in the XFCE desktop. Settings, removable drives and media, Storage tab. Will not happen again - in this computer! With my memory, I will forget the next time ;-) So it is the desktop, not apparently systemd, and 'cryptsetup' could see the situation before starting. If you want me to run strace or something, I still can. I will probably encrypt it this afternoon. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
