     The ???mount??? system call; see (gnu build file-systems).

I confess, I have not really thought about this before. But supposing somebody has in their /etc/config.scm:

  (file-systems 
   (cons*
    (file-system
      (device "my-root")
      (title 'label)
      (mount-point "/")
      (type "ext4"))
    (file-system
      (device "fileserver.example.com:/home")
      (title 'device)
      (mount-point "/home")
      (type "nfs4"))
    %base-file-systems))

Would the /home filesystem then get mounted on boot?

     The strategy is to stick to what upstream does, in general, and I???m not
     convinced splitting would buy us much (in terms of disk usage, for
     instance.)

In general I think that is a sensible strategy.  Splitting, would not buy us anything 
in terms of disk space, but I think it would mean less rebuilding when some configure 
option needs to be changed.
