Well, this is interesting.
It looks like Debian's new version is more than just systemd.
Trinity v14.0.2 Debian 8
When I plug in an encrypted USB disk, the password window opens as it always did, but now it's complaining about HAL not existing.
When I tried to open it through the Konqueror device view, it also failed. Attached are two screen grabs of the failures.
I'm not asking for this to be "fixed" in TDE, it seems that the underlying hardware abstraction has changed in some fundamental way. HAL isn't even in the repository for Debian 8. I expect someone will get around to harmonizing this at some point, I'm sure I'm not the only person who has encrypted external disks that used to work seamlessly.
The more things change.....
