GEOM allows us to do exactly this sort of thing in a non-hackish way, but for lack of time and fear of bikesheds (boy, did I get that wrong!) I havn't even thought of going near that feature-set. Various people have mumbled about automounting things in logical places and a number of gottchas have been raised. There are issues which needs to be hashed out, and security is a significant road-block Imagine a CDrom which says "mount me on /etc" :-( The concept I'm toying with currently is something like this: When a new device arrives, we scan it (somehow) for identifiers (volumen names, UUIDs, whatever) then look it up in /var/db/volumes. If there is a match (wildcards allowed) we mount it where /var/db/volumes tells us to, If there is no match, we don't mount it until the user tells us to. In a graphical env we could pop up a window asking for mountpoint and with a "save" checkbox which creates a /var/db/volumes entry. Some of this, btw, crosses into devd(8) territory. Anyway, I think this is a very interesting area of future development and I think we can do some really cool things, but it will not happen for 5.0-R. It could _maybe_ happen for 5.1-R if somebody with time and skill comes forward right after 5.0-R. In the meantime, lets focus on what we put on our platter already.
