[PATCH] multiple changes in generate_netboot_iso in actio_buildiso.py

Hi, Some changes in the generate_netboot_iso function/code: - Users had to supply all system names on the commandline which they wanted to include in the ISO boot menu. This patch changes that behaviour; all systems are included by default now. You can still provide an override with the --systems parameter, thus making this feature more consistent with what one might expect from reading the help. - While at it I tried to make the code more readable and removed some unneeded iterations. - Prevent some unneeded kernel/initrd copies. - You can now override ip/netmask/gateway/dns parameters with corresponding kernel_options. - Fixed a bug for SuSE systems where ksdevice should be netdevice. - If no ksdevice/netdevice (or equivalent) has been supplied via kernel_options try to guess the proper interface to use, but don't just use one if we can't be sure about it (e.g. for multihomed systems). https://github.com/jmaas/cobbler/commit/9191c7f30ffbac0292b36a7b45e34ce22...
