The right thing, I think, is to have a config_non_cannonical_msdos_filesystem
which
(a) doesn't transform names heading into msdos, and
(b) treats names which don't appear in the directory as "virtual
symlinks" to the aliased names.
This will eat some cache, and some processing time, but it
should be possible to re-write the fat file system to make
this work.
This is no worse, in principle, than an automounter.
