I would agree that, out of the box, memory management parameters should
be set to reliable levels. However, in the area of memory management
(as well as some other kernel parameters), one size does not fit all.
Tunable parametrs are of interest and benefit to myself, and others, and
there is no need to reduce their number or eliminate them. They are a
great feature of Linux, and I would like to see even more put in. (Not
TOO many. Another, more important feature of Linux is "Lack of Bloat".)
That's my 20% of a dime.
