Just curing the symptoms instead of the problems will not help to get
there any sooner. There might be stuff where the stuff at hand is not
easily fixed, but that is no reason to not consider it not worth doing.

to a broken build system and putting the dirt under the carpet, so
people do no longer get dirty feet walking around most of the time).
