      Your explanation is good and it suggests the help is correct.  But
      that the help is correct speaks to my point.  It just seems a
      non-essential, quite optional item should not be marked as default
      to build.  It should be the other way around.<br>

        <div class="gmail_extra">A lot of the extra features in the
          kernel are there to allow for easier debugging when doing
          kernel development.  They typically add extra load to deal
          with and slow down the system, overall.  (It's minimal, but
          it's still a performance hit).<br>
          <br>
          In the two you listed, Kprobes is just such a feature.  It
          helps with debugging, so if you're a user who isn't doing
          kernel development, you don't need it and probably wouldn't
          know what it was.  cgroups... I don't know that there's any
          benefit to having cgroups unless you know how to use them.  On
          their own, I believe their only use is if you have
          applications that hook into them to limit resource usage.  So,
          I imagine if you don't know what cgroups are, you really don't
          need them.  (And, again, they include a tiny performance hit)<br>
          <br>
          So, to answer your question, the features that have that
          listed seem like they're more for power users or kernel
          developers, so to make sure you get the most performance out
          of your custom rolled kernel, you shouldn't include them
          unless you need them.<br>
          <br>
          That's my take at least.<br>

              Several kernel options are marked to install as default,
              yet the help instructs "If unsure, say N." or the
              equivalent.  This isn't a big deal and I'm certainly not
              losing sleep over it, but it seems contradictory.  Does it
              make sense?  If so, what's the logic?<br>

              Two examples from linux-3.8.1 General setup:<br>

              General setup/Control Group support ---> - Say N is
              unsure.<br>
              General setup/Kprobes - If in doubt, say "N".<br>
