- extend includeKernelParameters to parse files
  * before this patch only /proc/cmdline was read in
    now an optional paramters allows to change this
- prevent duplicates in resolv.conf managed by setupDNS
  * if setupDNS is called multiple times it added the same
    line again and again. This patch checks if the entry
    exists before adding it
- s390: introduced new function loadNetworkCardS390
  * allow preconfiguring of s390 network cards. The function checks
    on a given host (DASD 191 in our case) for a parm file with the
    name <LINUX_USER_ID>.PARM-S11. If it is found the parameters
    normally read from the kernel cmdline are read from there and
    exported. The exported data takes effect later to set up the
    network with the setupNetworkInterfaceS390 function.
    The check for the parm file can be deactivated by a one-time
    flag file '/etc/deactivate_s390_network_config_from_dasd'
    which is removed when found and evaluated
