Red Hat Bugzilla – Bug 125298
need way to carry over old lease to dhclient
Last modified: 2007-11-30 17:10:44 EST
In the readonly nfs root case we don't want to down the interface
before requesting an ip, as that kills the root filesystem. We need a
flag that disables this behaviour.

patch to implement -ns
This patch works for me if i put DHCLIENTARGS=-ns in
Hmmm, in fact the interface isn't downed, the hang is just when doing
"ifconfig eth0 0 up". This should be a nop since the interface is
already up. I dunno whats causing this, will investigate. Hold on the
patch until this has been further analyzed.
Ah, so the "0" is whats causing it. It sets the interface ip to
0.0.0.0, which is needed when you broadcast for the initial dhcp ip.
What we need to do is to make it do a renew instead, and carry over
the lease from the old dhcp call.

Don't set ip to 0.0.0.0 if we have a lease for the current ip already
With this patch things work if i carry over the dhcp client leases
file from the initrd.
Patch applied to dhcp-3_0_1rc12-8
