the whole thing generic. That is, /conf/base, /conf/default,
/conf/${ipba}, and /conf/${ip} are all handled the same way.
Introduce an NFS remounting feature via the /conf/base/<dir>/diskless_remount
so you can avoid dup'ing system directories in /conf (described in rc file).
Introduce a memory filesystem sizing feature via the /conf/base/<dir>/md_size
file that allows you to override the default memory filesystem size.
Introduce a file containing relative paths to remove for each memory filesystem
directory as /conf/base/<dirname>.remove.
Make the cpio feature more generic (applies to any filesystem) (aka
/conf/base/<dirname>.cpio.gz).
Allow any root directories to be created as a memory filesystem via the
/conf/*/* mechanism.
Replace the copyright notice with a reference to the COPYRIGHT file and
do other cleanups.
