Comment # 36 on bug 953522 from Stefan Dirsch

Anyway, I seriously doubt the problematic here has been fully understood by the
YaST side. I'll try to explain the previous and current behaviour and what we
want to achieve here:

SLE11:
1) packages with appropriate hardware supplements have been autoselected for
installation during and *after* installation. Great!
2) recommended packages have been autoselected for installation during and
*after* installation. Customers weren't so happy
    about the latter.

SLE12/SLE15(SP0) (also openSUSE/Leap/TW of course)
1) packages with appropriate hardware supplements are autoselected for
installation *during* installation, but *not* afterwards, 
  e.g. after you add a repo like the NVIDIA one, the autoselection for the
right packages of this repo no longer work (this bug here
  is about!)
2) recommended packages are autoselected for installation *during*
installation, but no longer also *after* installation due to 
   a feature request, which then broke autoselection of packages with hardware
supplements (although in this FATE it was claimed
   this would not happen, LOL)

SLE15-SP1/fate#325513/this bug
The intention here is to fix autoselection again for packages with appropriate
hardware supplements *after* installation.

If I understood this correctly this would mean one needs to set 'onlyRequires'
to "true" given that "system supporting packages"
includes hardware supplements. In case you don't know what hardware supplements
means, here an example:

# rpm --supplements -q xf86-video-intel
modalias(xorg-x11-server:pci:v00008086d00001132sv*sd*bc*sc*i*)
modalias(xorg-x11-server:pci:v00008086d00002562sv*sd*bc*sc*i*)
[...]

So I would expect that we would need the settings 

during installation:  ignoreA.R.`=false,  `onlyRequires`=true 
after installation:    ignoreA.R.`=true,  `onlyRequires`=true 

And, BTW,  I no longer believe IGNORE_RECOMMENDED maps to "onlyRequires". This
might have a complete different
meaning ...

Reopening. This should not be closed before it hasn't been understood by all
sides!
