Subject: [PATCH] network: add save_netinfo, fix problems with nfs->NM
|
||
|
|
takeover
|
||
|
|
|
||
|
|
For NetworkManager to properly take over a NFS-root system, we need to
|
||
|
|
have the interface name(s) in /tmp/net.ifaces and save the dhclient
|
||
|
|
lease. This lets the ifcfg module do its magic.
|
||
|
|
|
||
|
|
save_netinfo should properly write out /tmp/net.ifaces when needed, and
|
||
|
|
copies the dhclient files into place.
