Comment # 57 on bug 1189841 from Martin Wilck

I've pushed the related changes to suse-module-tools now:

SLE-15-SP3: MR 255494
SLE-15-SP2: MR 255495
SLE-15-SP4: SR 255496

Once these are released, the reverts of Michal's patch can be re-reverted:

 * SLE15-SP2/3: 7d435688cfe6 ("Revert "rpm: Abolish scritplet templating
(bsc#1189841)." (bsc#1190598)")
 * SLE15-SP4: eebdae782118 ("Revert "rpm: Abolish scritplet templating
(bsc#1189841)."")


NOTE TO MAINTENANCE / QA: 

These changes fundamentally change the way how kernel installation and update
works. This will be enabled by re-reverting the above mentioned revert commits.
Once these re-reverts have happened, special attention in QA for the kernel
update will be required, in particular for SLED and Leap with the -extra and
-optional packages (I suppose if something goes wrong in SLE it will be
detected anyway). It'd be good to explicitly test installation / update of some
of the "KMPs" shipped with kernel-source as well.
