Because they require maintenance, cause bug reports (such as Marcy's), etc., etc. They're not going away tomorrow, but please plan ahead. One of the complaints we hear is that "doing X on SLES for the mainframe is different from how it's done on RHEL." Red Hat hears the same, in reverse. SUSE and Red Hat both approached IBM to ask them to write and maintain a replacement set of tools for these sorts of scripts. That way, the tools to perform persistent and transient configuration will be the same across distributions. I haven't looked, but I'm guessing Ubuntu for the mainframe is using them as well. So, IBM came up the lszdev and chzdev utilities. To provide compatibility, I modified the existing *_configure scripts to use them instead of the previous logic. Moving forward, SUSE will be using the lszdev and chzdev commands in our own tools where the *_configure scripts have been used in the past. The linuxrc program to set up the installation environment is already doing that. The wrapper scripts were written solely as a means of translating the old semantics into the ones required by IBM's commands. The lszdev and chzdev commands provide a lot more functionality than the old *_configure scripts did. There will be no changes to the *_configure scripts unless there's a bug, or for some reason IBM changes the parameters their commands accept or require. If you set an environment variable of DEBUG to "yes", the *_configure scripts will display the chzdev command that gets executed, as well as actually executing it. Besides helping in debugging, this will allow anyone wishing to get ahead of the curve to see exactly what command needs to be executed to accomplish the same task as before. The old scripts will not be removed from the SLES12 product. At this point, we're not sure if they will be removed from future service pack levels of SLES15 or not. They almost certainly will not be part of the follow-on version after SLES15. (After what happened between SLES12 and SLES15, I'm not going to even try and outguess Product Management as to what name that's going to be.) Finally, this is Open Source Software. If you decide you're simply not going to move to the new commands from IBM, you're welcome to make and keep copies of the *_configure scripts for your own use, for ever and ever.
