This has nothing to do with updating the OS itself.

That said, I assume host:/export-to-rpi/local is only used by a
single host.
It gets tricky with shared /usr/local, since the package registration
is in a different path and ports/packages may also touch /etc - e.g.
/etc/shells, or add service users for a specific software.
It is possible to do, but unless you are very carefull things can
easily get messy.
Same goes for /tmp.
Needless to say that swap isn't to be shared at all...
But I'm not sure if swap on NFS is completely deadlock free.
