How about this:

Rather than making the split between / and /usr, make it between
Before and After basic.target (as basic.target is roughly what
traditionally would require files to be on /). This would require us
to associate files to be readahead with services, but based on what
you wrote in a previous message that should be easy enough.

I guess that would give you roughly the same effect, but without
relying on a split which is going away.

I still think that is far, far from perfect, but it might be a start
(especially the association between files and services might turn into
something very useful).

Cheers,

Tom
