This is something you'd have to ask your OS vendor. If they don't
support netwokrd, they will support something else, and maybe it has a
way to run in early boot or initrd.

Booting without /tmp/ mounted during early boot is simply not
supported from upstream, sorry, can't help you there. Please contact
your OS vendor if they can help you.

If /usr/ is split off it *must* be mounted even earlier than /tmp/: it
must be mounted in the initrd, nothing else is supported, sorry.

If /var/ is split off it must be mounted at the same point as /tmp/,
i.e some time in early boot, not necessarily in the initrd though.
