If I have a hot-pluggable device (SD card, USB drive, hot-plug SATA/SAS
drive and rack, etc.), can I put LVM on it such that when the device is
connected to a Debian system with a graphical desktop (I use Xfce) an icon
is displayed on the desktop that I can interact with to display the file
systems in my file manager (Thunar)?
In the past: definitely not. Currently: no idea.
I suspect not, because I think the behavior on disconnection is still
poor (you want to be extra careful to deactivate all the volumes on the
drive *before* removing it, otherwise they tend to linger "for ever").
I guess that's one area where partitions are still significantly better
than LVM.
