[RFT PATCH] Delay netroot mounting by 1 second

[Seewer Philippe <philippe.seewer-omB+W0Dpw2o@public.gmane.org>]

While testing in our production environment, I discovered
that the time between interface configuration and trying 
to mount the nfs root is too short if the dhcp-server 
provides an mtu. Having to set a mtu means that netroot
executes 'ip link down', set's the mtu and the does
'ip link up' again.

This results in the mount error "No route to host", because
the network equipment has not had enough time to "shake hands". 
The patch below adds a sleep 1 after interface configuration, 
to give the equipment enough time.

Could anyone with a similar environment (and possibly with
a netroot server reachable only via default route) test this
with and without this patch to confirm?

Thank you,
Philippe
