Is there any 'new' thinking in terms of filesystem layout?  The old
tree sort of made sense in the old days of tiny, slow disks that had
to be micro-managed.  Now it seems like it would be good to isolate
the system executables and maybe even the config files in a small
section that could be mounted read-only except when planning to do
updates, with an option to share space among any or all of the
writable parts.
