This brings linuxrc.s390 and friends to the latest version as posted here https://www.redhat.com/archives/anaconda-devel-list/2009-February/msg00392.html plus some updates after that. Changes: - update usage of udev to rawhide - no more telnetd for network login during install - adapt readcmsfile to automatic loading of device driver modules - refactor main part into function init_main - consider renaming of network device driver module from ctc to ctcm - refactor control unit lookup tables into separate file - no more rely on kernel versions to detect device driver features - upstream qeth driver supports IPv6 on HiperSockets in layer3 mode - no more manual (un)loading of device driver modules - correctly handle default MAC address for layer2 qeth devices - no more kill udevd at end of linuxrc.s390 - write network device configuration to correct new place (ifcfg) Splitting up into single patches is impossible without merge conflicts. --- loader/controlunits.sh | 56 +++++ loader/linuxrc.s390 | 575 +++++++++++++++++++----------------------------- 2 files changed, 288 insertions(+), 343 deletions(-) create mode 100644 loader/controlunits.sh diff --git a/loader/controlunits.sh b/loader/controlunits.sh new file mode 100644 index 0000000..e99db36 --- /dev/null +++ b/loader/controlunits.sh @@ -0,0 +1,56 @@ +# controlunits.sh: define some common control unit mappings +# Copyright (C) IBM Corp. 2009 +# Author: Steffen Maier <maier@xxxxxxxxxx> +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; version 2 of the License only. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
