Description Flags
patch to implement -ns
none
Don't set ip to 0.0.0.0 if we have a lease for the current ip already none

Description Alexander Larsson 2004-06-04 15:40:23 UTC
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

Comment 2 Alexander Larsson 2004-06-04 15:41:32 UTC
This patch works for me if i put DHCLIENTARGS=-ns in
/etc/sysconfig/network.

Comment 3 Alexander Larsson 2004-06-04 16:20:31 UTC
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.

Comment 4 Alexander Larsson 2004-06-04 16:57:00 UTC
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.

Comment 6 Alexander Larsson 2004-06-07 20:03:57 UTC
With this patch things work if i carry over the dhcp client leases
file from the initrd.
