  Files in /proc and /sys aren't general files.
They are a virtual filesystem provided by Linux.
sysfs is  http://en.wikipedia.org/wiki/Sysfs
procfs is http://en.wikipedia.org/wiki/Procfs

So, it isn't needed that you copy them to ramdisk.
But if procfs isn't mounted , you can manually mount procfs.
For example
$ mount -t proc proc proc/
$ mount -t sysfs sys sys/

And the ramdisk already has enough packages and files to connect network.
Important thing is to successfully load ethernet driver on L4/L4linux 
environment.
If you succeed in working ethernet driver, you can use commands 'ifup' 
and 'ifdown','ifconfig' to connect network.
And you can check whether ethernet driver is loaded or not if you do 
'dmesg | grep ethernet'.
