Re: Network changes between 4.x and 5.1RC3 ?

I tried to boot the old 4.0.1 kernel again, and with a whole lot of juggling had 
/usr/4.0.1/ untarred managed to mount, and ifconfig and get things running.

It runs beautifully. Fast, no delays and hung connections.

Since HDD0 and HDD1 are setup identically, both have boot, /usr etc, could I 
unpack 4.0.1 /usr on HDD1, and somehow tell the boot loader when booting HDD0 to 
use HDD1 for kernel and rootdev?
