Other thing I need to test better is boot with PXE with NBD of NFS 
(since these are persistent, no copytoram is done by default).

1) DHCP is requested again on real-root. I guess, is most cases, there 
is no issues since is re-assigned the same IP address. (this bug 
introduced recently since rc.conf enabled "network")
Solutions:
a) If this happens suggest the to the user use copytoram=y
b) Use copytoram=y in NBD/NFS by default (this is always done for HTTP), 
user can change this behaviour.
c) Disable DHCP service from relevant hooks.

2) Stopping network on shutdown, if network is stopped before reach 
shutdown-initramfs againt this does not look good.
Solutions:
a) See how to skip network on shutdown.
b) Same point (1.b)
