Thomas Renninger 7bf826553e Accepting request 251837 from home:trenn:branches:Base:System
- Add ip= and root=nfs.. to dracut internal cmdline to make nfsroot working
  (bnc#896464)
* Add 0160-nfs-Add-ip-.-and-root-nfs.-parameters-to-internal-dr.patch
- Fix error message in case there is no internal dracut cmdline added
  Simple fix
* Add 0161-Fix-error-message-when-there-are-no-internal-kernel-.patch
- Request DHCP lease instead of getting/applying the offer
  No bug number, but Pawel rated this high prio. This should hit SLE12 still.
* Add 0162-network-Request-DHCP-lease-instead-of-getting-applyi.patch
