Yeah the cases are all covered, I don't know of docs other than the
code or the list archives.

I didn't follow the decision too closely but AFAIK the reason for the
design is to be able to move to trash with a rename() instead of a
copy. This avoids disk space issues and makes move-to-trash an atomic
operation (and faster). Also, it means that the trash on a shared
filesystem is shared. So if I throw something away on a workgroup
server anyone in the workgroup can remove it from the trash. Hmm, also
it means that for removable media the trash travels with the media, so
if I throw something away on a floppy it stays on the floppy instead
of copying to/from the hard drive. There may be other reasons.

The trash goes on the root of the filesystem if the root is writable
and otherwise falls back to ~/.Trash, IIRC.

I believe there is no need to keep a list of trash dirs per user since
the trash is located via a fixed algorithm. Nautilus just looks at the
root of all mounted filesystems plus ~/.Trash and merges those into
the list of files in the virtual trash:/// location.

Is this preference useful? ;-)

I think we can hack around it somehow.
