As I understand it, the kernel patch does group by TTY. Personally I think |
23 |
that's just one way of doing it and there could be others. So it's more proof- |
24 |
of-concept than TheOneTrueWay(tm) |

The config and bash commands method from RedHat does things slightly |
27 |
differently. Prevailing opinion on /. is that the patch method is cleaner but |
28 |
more restrictive, which the userspace method is more configurable but requires |
29 |
root. |

Perhaps distros will pick up on this and offer other criteria, maybe something |
32 |
like a profile selectable at boot-time or maybe even runtime. |

What *I* would like to see is flash goes into it's own group and gets |
35 |
throttled. Everything else running under KDE is in a different group and left |
36 |
to run full speed |
