# prerequisites of this script to run inside the installer initrd:
|
|
# - udevadm and udevd need to be there
|
|
# - have /etc/udev/udev.conf with at least one comment line as content
|
|
# - if necessary, have udev rules
|
|
# - lsznet.raw and znetcontrolunits from s390utils-base in /lib/s390-tools
|
|
# - pack kernel modules and module-init-tools (no longer use busybox for that)
|
|
# - "multi on" in /etc/host.conf [RH bugs 486457,486461,483244]
|
|
|
|
# TODOs:
|
|
# - make sure driver modules get loaded automatically
|
|
# - udev rule for lcs/ctcm vs. cu3088
|
|
|
|
# debug: set -x
