Comment # 34 on bug 1029129 from Michael Schr�der

My point is the openSUSE:Factory will be SLE16 at one point, so we should not
remove functionality required for SLES. Factory is supposed to be a testbed for
SLES, so we should diverge as little as possible.

That doesn't mean we should not remove broken things. It's just that we need to
make sure that we don't remove things that are required by the SLES customers.

(Of course it's also ok to offer them a better way to do what they want.)

As for DISABLE_RESTART_ON_UPDATE, my impression was that this functionality is
required by our sles customers.
