I tought that a sysfs attribute would have been enough to disambiguate
the rules.

Why? The names do not change, as they depend on the ide bus positions.

Multiple names have the downside that admins will have to modify the
"standard" rules, while with different rules they could just add the
appropriate aliases at the end of the config file.

I tried it, but it does not work. (And what about /dev/tty?)
