It goes back /four years/. Wow.

I don't think I can blame the IBMers for getting tired of customer confusion, but this is a case of mucking the tech for a political reason. (Here "political" because they're forcing the hand of the distributors for failing to configure a better module list.) >From the commit ... "There have been too many cases where people were missing the 'vmcp' device node and unable to send z/VM CP commands. So let's make sure that on distros it will always be present." I hate to see the loss of the CONFIG_VMCP=m option. But there's been consistent "INITRD abuse" for more than a decade, things which should be static but are left as loadable. This is what comes of it. And now SUSE layers a patch on top of the official kernel ... puh-leeze!!

Good practice to ignore certain errors from 'modprobe', and this is a prime example. So if you happen to have a shell script that does a 'modprobe vmcp' before doing a 'vmcp' command, it should re-direct stderr (of the first part) to /dev/null. If there's an actual error, the latter command will fail and will clue the user that something's wrong. Think about it. -- Rick Troth Senior Software Developer Velocity Software Inc.
