Re: [PATCH rhel6-branch] network: using more than one NICs (iSCSI) (#638131, #634016)

To answer good question Chris Lumens posed on #anaconda IRC
concerning reconfiguration of NIC enabled (using cmdline configuration)
to fetch kickstart by kickstart network command:

- In rhel 5.6 we apply the kickstart configuration of first network command,
  other network commands only set configuration for post install reboot.

- In rhel 6.0 all network commands only set configuration that is applied
  only after reboot.
  (There is one issue that devices having ONBOOT=yes set will be brought
  up before package installation, when network configuration is written
  into ifcfg files. This might cause routing problems, though none has been
  reported yet. It is to be handled in separate bug.)

- With the patchset, network commands concerning already activated device
  only set post-install configuration - the device is not reconfigured in
  installer - same as in 6.0. Other devices having new --activate option
  are brought up in loader. (The ONBOOT=yes issue remains as in 6.0)

Do we want to change it back to the 5.6? I'm not against it but I think it
would be better to do it in a separate bug.

I noticed that the patchset is changing behaviour from 5.6 and 6.0 in the case
when network is not brought up before parsing ks. In 5.6 and 6.0
we would bring network up using first network command, whereas with
this patchset, it would be so only if --activate is present in the first
command. I will fix this so that if network is not up, --activate flag
(lack of it) is ignored and the device is activated.
