I remember that, back in the SunOS 4 and earlier days.  We
called it a "dataless" configuration: / and swap were local, but
/usr, /usr/local, and home directories came via NFS.  It wasn't
a bad way to do things.

When Solaris 2 came along, essentially everything was
dynamically linked; statically linked binaries went into /sbin,
and my sense at the time was that 's' stood for 'static' (or
possibly 'standalone').  Nowadays, that is mostly system
utilities, whether statically linked or not, and so the meaning
has shifted again.
