I found this (userspace) tool that does that sort of thing, years
ago--thanks for reminding me:

          http://esky.sourceforge.net/

It looks like it hasn't been maintained since the latter part of the
Linux-2.2 era (~a decade), so I have no idea how well (or even /if/)
it works more modern incarnations of Linux or Solaris. Even if it does
turn out to be just completely-out-of-touch with the modern world, it
may make an interesting springboard for building a tool of your own.
