The whole FH can be shared by NFS root, except /var, which cannot
be shared entirely and /run (formerly /var/run) which cannot be shared
at all - talking about Debian's FH.
The problem is /var/lib which must be carefully separated in two
parts to distinguish applications which keep common data (eg apt) and
applications which keep hardware-related data (eg ntpd). Then a few
dirty tricks are necessary to make the two categories look like they are
all in /var/lib.
I don't know if the question of sharing the FH through NFS is
seriously addressed by the FHS; but, if it is, it fails.
