[PATCH openbmc 28/32] init: Add option to copy files into memory

[OpenBMC Patches]

From: "Milton D. Miller II" <miltonm at us.ibm.com>

Add an option to copy files from the rwfs to ram then run in ram.

This allows customizations like user ids and network settings to
be initialized from the read-write filesystem.
