Comment # 42 on bug 953522 from Michael Schr�der

#39: there was a change in libzypp, onlyRequires=1 will now still install
hardware packages.

onlyRequires=1 used to be "ignore all package recommends/supplements", it's now
"ignore all except system dependencies".

There currently is no way to ignore all recommends/supplements.

"ignoreA.R.=1" makes the solver not look at the recommends/supplements for
installed packages that are not updated. I.e. if you do a "zypper install foo"
you will not get something installed because of a recommends of a package that
has nothing to do with the request.
