I'd love to use a db for a filesystem for many of my directories.

Granted, it might just be sub-optimal in certain scenarios, but I already have to logically partition my data into big blobs that are rarely accessed and stuff that must go into the SSDs already. Maybe just giving that FS a hatch to deal with the stuff that must be special and odd/weird is ok. I don't really want the DB magic for my swap files anyway.
